# Print Quality Issue - Dotted/Pixelated Text Solution
|
||||
|
||||
## 🔍 Problem Identified
|
||||
|
||||
**Issue:** Text appears dotted/pixelated on printed labels (like dot-matrix printer output)
|
||||
- PDF looks perfect on screen ✅
|
||||
- But printed output has dotted text ❌
|
||||
- Not smooth/sharp like expected
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Root Cause
|
||||
|
||||
The problem is in the **print pipeline**, not the PDF:
|
||||
|
||||
1. **PDF is generated correctly** at 1200 DPI with vector fonts
|
||||
2. **Printing process rasterizes** (converts to bitmap) the PDF
|
||||
3. **Rasterization happens at LOW resolution** (150-300 DPI typically)
|
||||
4. **Result:** Dotted text instead of smooth vectors
|
||||
|
||||
### Why This Happens:
|
||||
|
||||
```
|
||||
PDF (Vector) → SumatraPDF → Low DPI Raster → Printer Driver → Dotted Output
|
||||
↑ Problem here! Converts to low-res bitmap
|
||||
```
|
||||
|
||||
The printer receives a **bitmap image** at low resolution, not the original vector graphics.
|
||||
|
||||
---
|
||||
|
||||
## ✅ Solutions Implemented
|
||||
|
||||
### **Solution 1: Printer Quality Configuration (CRITICAL)**
|
||||
|
||||
Updated `print_label.py` to configure printer for HIGH QUALITY before printing:
|
||||
|
||||
```python
|
||||
# New function: configure_printer_quality()
|
||||
- Sets PrintQuality = 600 DPI (not draft mode)
|
||||
- Sets TTOption = DMTT_BITMAP (sharper text)
|
||||
- Configures paper size to 35mm x 25mm
|
||||
```
|
||||
|
||||
**This is now automatic** - runs before every print job.
|
||||
|
||||
---
|
||||
|
||||
### **Solution 2: GhostScript Printing (BEST QUALITY)**
|
||||
|
||||
Added GhostScript as primary printing method:
|
||||
|
||||
**Why GhostScript is Better:**
|
||||
- ✅ Maintains **vector graphics** (not rasterized)
|
||||
- ✅ Renders directly to printer at **1200 DPI**
|
||||
- ✅ Perfect text anti-aliasing
|
||||
- ✅ No intermediate bitmap conversion
|
||||
|
||||
**Printing Priority:**
|
||||
1. **GhostScript** (if installed) - BEST quality
|
||||
2. SumatraPDF (fallback) - Good quality
|
||||
3. ShellExecute (fallback) - Uses default PDF viewer
|
||||
4. Open file (last resort) - Manual printing
|
||||
|
||||
---
|
||||
|
||||
## 🚀 How to Get Best Quality
|
||||
|
||||
### **Option A: Install GhostScript (Recommended)**
|
||||
|
||||
1. **Download GhostScript:**
|
||||
- Go to: https://ghostscript.com/releases/gsdnld.html
|
||||
- Download: "GPL Ghostscript 10.04.0 for Windows (64 bit)"
|
||||
|
||||
2. **Install:**
|
||||
- Run installer
|
||||
- Use default installation path
|
||||
- No special configuration needed
|
||||
|
||||
3. **Test:**
|
||||
```powershell
|
||||
python print_pdf_ghostscript.py
|
||||
```
|
||||
Should show: ✅ GhostScript found
|
||||
|
||||
4. **Print:**
|
||||
- Just run your GUI normally
|
||||
- It will automatically use GhostScript
|
||||
- You'll see: "Using GhostScript for high-quality vector printing..."
|
||||
|
||||
**Result:** Perfect, sharp text with no dotting!
|
||||
|
||||
---
|
||||
|
||||
### **Option B: Configure Printer (Without GhostScript)**
|
||||
|
||||
If you can't install GhostScript, the code now **automatically** configures printer quality.
|
||||
|
||||
But you should also manually check:
|
||||
|
||||
1. **Open Printer Preferences:**
|
||||
```powershell
|
||||
.\configure_label_size.ps1
|
||||
```
|
||||
|
||||
2. **Set Quality to HIGHEST:**
|
||||
- Look for "Print Quality" or "Resolution"
|
||||
- Set to: **600 DPI** or **Best** or **High Quality**
|
||||
- NOT "Draft" or "Normal" or "Economy"
|
||||
|
||||
3. **Disable Dithering:**
|
||||
- Look for "Dithering" or "Halftone"
|
||||
- Set to: **None** or **Off**
|
||||
|
||||
4. **Set Graphics Mode:**
|
||||
- Look for "Graphics" or "Text Quality"
|
||||
- Set to: **Vector** or **High Quality**
|
||||

## 📊 Quality Comparison
|
||||
|
||||
| Method | Text Quality | Speed | Installation |
|
||||
|--------|--------------|-------|--------------|
|
||||
| **GhostScript** | ⭐⭐⭐⭐⭐ Perfect | Fast | Requires install |
|
||||
| **SumatraPDF + Quality Config** | ⭐⭐⭐⭐ Very Good | Fast | No install needed |
|
||||
| **SumatraPDF (default)** | ⭐⭐ Dotted | Fastest | No install needed |
|
||||
|
||||
---
|
||||
|
||||
## 🧪 Testing
|
||||
|
||||
### Test 1: Check Current Method
|
||||
```powershell
|
||||
# Start GUI
|
||||
.\venv\Scripts\python.exe label_printer_gui.py
|
||||
|
||||
# Watch console output:
|
||||
# Should say one of:
|
||||
# "Using GhostScript for high-quality vector printing..." ← BEST
|
||||
# "Label sent to printer via SumatraPDF..." ← OK
|
||||
```
|
||||
|
||||
### Test 2: Verify GhostScript
|
||||
```powershell
|
||||
python print_pdf_ghostscript.py
|
||||
```
|
||||
|
||||
Expected output:
|
||||
```
|
||||
✅ GhostScript found at: C:\Program Files\gs\gs10.04.0\bin\gswin64c.exe
|
||||
GhostScript is available for high-quality PDF printing
|
||||
```
|
||||
|
||||
### Test 3: Print Test Label
|
||||
```powershell
|
||||
python test_quality.py
|
||||
```
|
||||
|
||||
Check printed output:
|
||||
- ✅ Text should be **smooth and sharp**
|
||||
- ✅ No dotted appearance
|
||||
- ✅ Crisp edges on checkmark image
|
||||
- ✅ Professional quality
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Troubleshooting
|
||||
|
||||
### Still seeing dotted text?
|
||||
|
||||
#### Check 1: Printer Driver Quality
|
||||
```powershell
|
||||
# Run configuration script
|
||||
.\configure_printer_quality.ps1
|
||||
|
||||
# Manually verify:
|
||||
# Settings > Printers > Labels > Printing preferences
|
||||
# Quality = HIGHEST (600 DPI or more)
|
||||
```
|
||||
|
||||
#### Check 2: Print Method Used
|
||||
Look at console output when printing:
|
||||
- **GOOD:** "Using GhostScript..."
|
||||
- **OK:** "Printer configured: 35x25mm @ HIGH QUALITY"
|
||||
- **BAD:** "Could not configure printer quality"
|
||||
|
||||
If you see "Could not configure printer quality":
|
||||
- Printer driver doesn't support programmatic quality changes
|
||||
- MUST configure manually in printer preferences
|
||||
|
||||
#### Check 3: Label Material
|
||||
- **Wrong:** Plain paper (not designed for thermal printing)
|
||||
- **Right:** Thermal labels (heat-sensitive or transfer)
|
||||
|
||||
Wrong label material can cause poor quality even with correct settings.
|
||||
|
||||
#### Check 4: Printer Hardware
|
||||
```powershell
|
||||
# Print self-test from printer
|
||||
# (Usually hold button while powering on)
|
||||
```
|
||||
|
||||
If self-test also shows dotted text:
|
||||
- Printer may be in draft mode
|
||||
- Check printer's physical control panel
|
||||
- Look for "Quality" or "Darkness" dial/setting
|
||||
- May need firmware update
|
||||

## 📝 Technical Details
|
||||
|
||||
### Why Dotted Text Happens:
|
||||
|
||||
**Normal printing workflow:**
|
||||
```
|
||||
PDF → Printer Driver → Sharp output
|
||||
```
|
||||
|
||||
**What was happening:**
|
||||
```
|
||||
PDF (vector, 1200 DPI)
|
||||
↓
|
||||
SumatraPDF rasterizes at LOW DPI (150-300)
|
||||
↓
|
||||
Bitmap sent to printer
|
||||
↓
|
||||
Printer prints bitmap → DOTTED TEXT
|
||||
```
|
||||
|
||||
**What we fixed:**
|
||||
```
|
||||
Method 1 (GhostScript):
|
||||
PDF (vector) → GhostScript → Printer @ 1200 DPI → SHARP TEXT
|
||||
|
||||
Method 2 (Quality Config):
|
||||
PDF → Configure printer to 600 DPI → SumatraPDF → Better quality
|
||||
```
|
||||
|
||||
### Key Settings:
|
||||
|
||||
1. **PrintQuality = 600**: Tells Windows to render at 600 DPI minimum
|
||||
2. **TTOption = 2 (DMTT_BITMAP)**: Renders TrueType fonts as graphics (sharper)
|
||||
3. **GhostScript -r1200**: Renders PDF at full 1200 DPI resolution
|
||||
4. **TextAlphaBits=4**: Anti-aliasing for smooth text edges
|
||||
|
||||
---
|
||||
|
||||
## 🎓 Recommendations
|
||||
|
||||
### For Production Use:
|
||||
|
||||
1. **Install GhostScript** on all computers
|
||||
- One-time setup
|
||||
- Always best quality
|
||||
- No manual configuration needed
|
||||
|
||||
2. **Keep PDF backup enabled**
|
||||
- Review PDFs to confirm they look correct
|
||||
- PDFs are always high quality
|
||||
|
||||
3. **Test periodically**
|
||||
- Print quality can change after:
|
||||
- Windows updates
|
||||
- Driver updates
|
||||
- Printer hardware changes
|
||||

# Label Printing - New Features Guide
|
||||
|
||||
## Overview
|
||||
|
||||
The label printer now supports:
|
||||
1. **Multiple Templates** - Choose between OK and NOK labels
|
||||
2. **Multiple Copies** - Print multiple labels in one operation
|
||||
|
||||
## File Format
|
||||
|
||||
The monitored file (`check.txt`) now supports an extended format:
|
||||
|
||||
```
|
||||
ARTICLE;NR_ART;SERIAL;TEMPLATE_TYPE;COUNT
|
||||
```
|
||||
|
||||
### Parameters
|
||||
|
||||
| Parameter | Position | Description | Values | Default |
|
||||
|-----------|----------|-------------|--------|---------|
|
||||
| ARTICLE | 1 | Article/Command number | Any text | Required |
|
||||
| NR_ART | 2 | Article number | Any text | Required |
|
||||
| SERIAL | 3 | Serial number | Any text | Required |
|
||||
| TEMPLATE_TYPE | 4 | Template selection | 0 = OK, 1 = NOK | 0 (OK) |
|
||||
| COUNT | 5 | Number of copies | 1-100 | 1 |
|
||||
|
||||
## Templates
|
||||
|
||||
### Template Files
|
||||
|
||||
- `conf/label_template_ok.svg` - Template for OK labels (TEMPLATE_TYPE=0)
|
||||
- `conf/label_template_nok.svg` - Template for NOK labels (TEMPLATE_TYPE=1)
|
||||
- `conf/label_template.svg` - Default fallback template
|
||||
|
||||
### Customizing Templates
|
||||
|
||||
Edit the SVG files to customize the layout:
|
||||
- Both templates use the same variables: `{Article}`, `{NrArt}`, `{Serial}`
|
||||
- Modify colors, fonts, or layout as needed
|
||||
- Keep dimensions at 35mm × 25mm (landscape)
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Example 1: Print 1 OK Label
|
||||
```
|
||||
COM-2024-001;ART-12345;SN-20260213-001;0;1
|
||||
```
|
||||
|
||||
### Example 2: Print 3 OK Labels
|
||||
```
|
||||
COM-2024-002;ART-67890;SN-20260213-002;0;3
|
||||
```
|
||||
|
||||
### Example 3: Print 1 NOK Label
|
||||
```
|
||||
COM-2024-003;ART-11111;SN-20260213-003;1;1
|
||||
```
|
||||
|
||||
### Example 4: Print 5 NOK Labels
|
||||
```
|
||||
COM-2024-004;ART-22222;SN-20260213-004;1;5
|
||||
```
|
||||
|
||||
### Example 5: Backward Compatibility (Old Format)
|
||||
```
|
||||
COM-2024-005;ART-33333;SN-20260213-005
|
||||
```
|
||||
This will default to OK template with 1 copy.
|
||||
|
||||
## Testing
|
||||
|
||||
### Quick Test
|
||||
|
||||
1. **Start the application**:
|
||||
```powershell
|
||||
.\venv\Scripts\python.exe label_printer_gui.py
|
||||
```
|
||||
|
||||
2. **Select your printer** in the GUI
|
||||
|
||||
3. **Edit the monitored file** (default: `C:\Users\Public\Documents\check.txt`):
|
||||
```
|
||||
TEST-OK;123456;SN-001;0;2
|
||||
```
|
||||
|
||||
4. **Save the file** - The app will automatically:
|
||||
- Detect OK template (type=0)
|
||||
- Print 2 copies
|
||||
|
||||
5. **Test NOK template**:
|
||||
```
|
||||
TEST-NOK;789012;SN-002;1;1
|
||||
```
|
||||
|
||||
### PDF Testing
|
||||
|
||||
Use "Microsoft Print to PDF" to test without physical printer:
|
||||
- Select "Microsoft Print to PDF" in the GUI
|
||||
- PDFs will be saved to `pdf_backup/` folder
|
||||
- Check that the correct template was used
|
||||
|
||||
## Workflow
|
||||
|
||||
```
|
||||
File Modified
|
||||
↓
|
||||
Read Parameters (Article, NrArt, Serial, Template, Count)
|
||||
↓
|
||||
Select Template (OK or NOK)
|
||||
↓
|
||||
For each copy (1 to Count):
|
||||
├─ Generate PDF from SVG template
|
||||
├─ Replace variables {Article}, {NrArt}, {Serial}
|
||||
├─ Save to pdf_backup/
|
||||
└─ Print via SumatraPDF
|
||||
↓
|
||||
Clear file (write "-")
|
||||
↓
|
||||
Show success message
|
||||
```
|
||||
|
||||
## Safety Limits
|
||||
|
||||
- **Maximum copies**: 100 per operation
|
||||
- **Minimum copies**: 1
|
||||
- Invalid values default to 1 copy
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Template Not Found
|
||||
- **Symptom**: Message "Using SVG template: conf/label_template.svg"
|
||||
- **Cause**: `label_template_ok.svg` or `label_template_nok.svg` missing
|
||||
- **Fix**: Ensure both template files exist in `conf/` folder
|
||||
|
||||
### Wrong Template Printed
|
||||
- **Symptom**: NOK template used when OK expected
|
||||
- **Cause**: TEMPLATE_TYPE parameter incorrect
|
||||
- **Fix**: Check 4th parameter is 0 for OK, 1 for NOK
|
||||
|
||||
### Only 1 Label Printed
|
||||
- **Symptom**: COUNT parameter ignored
|
||||
- **Cause**: Invalid COUNT value or missing parameter
|
||||
- **Fix**: Ensure 5th parameter is a number between 1-100
|
||||
|
||||
## Technical Details
|
||||
|
||||
### File Parsing
|
||||
|
||||
The system tries:
|
||||
1. **Semicolon format**: `value1;value2;value3;value4;value5`
|
||||
2. **Key=value format** (fallback):
|
||||
```
|
||||
article=COM-2024-001
|
||||
nr_art=ART-12345
|
||||
serial=SN-001
|
||||
template=0
|
||||
count=3
|
||||
```
|
||||
|
||||
### Multiple Copy Handling
|
||||
|
||||
- Each label is printed sequentially
|
||||
- 0.5 second delay between copies
|
||||
- Progress shown in GUI for multiple copies
|
||||
- All copies use the same PDF template
|
||||
|
||||
### Backward Compatibility
|
||||
|
||||
Old format (3 parameters) still works:
|
||||
```
|
||||
ARTICLE;NR_ART;SERIAL
|
||||
```
|
||||
Automatically uses: OK template, 1 copy
|
||||
|
||||
## Log Files
|
||||
|
||||
Print actions are logged to `logs/print_log_YYYYMMDD.csv`:
|
||||
- Date/Time
|
||||
- Article, NrArt, Serial
|
||||
- Printer name
|
||||
- PDF filename
|
||||
- Template used
|
||||
- Number of copies
|
||||
- Success/Failure status

# Label Printing Workflow Analysis - Paper Size Issue
|
||||
|
||||
## 🔍 Problem Identified
|
||||
|
||||
**Issue:** Labels printing on 90cm continuous roll instead of 35mm x 25mm label
|
||||
- PDF is created with correct size (35mm x 25mm)
|
||||
- Printer receives PDF but ignores the page dimensions
|
||||
- Printer defaults to continuous roll mode
|
||||
- Label content prints at the end of a long paper strip
|
||||
|
||||
---
|
||||
|
||||
## 📊 Current Workflow Analysis
|
||||
|
||||
### Step 1: PDF Generation ✅ (Working)
|
||||
```
|
||||
print_label_pdf.py creates PDF:
|
||||
- Page size: 3.5cm x 2.5cm (35mm x 25mm)
|
||||
- Layout: 1/3 image + 2/3 text area
|
||||
- Quality: 1200 DPI, no compression
|
||||
```
|
||||
**Status:** PDF dimensions are CORRECT
|
||||
|
||||
### Step 2: Printing via SumatraPDF ❌ (Problem)
|
||||
```
|
||||
SumatraPDF command:
|
||||
-print-to <printer>
|
||||
-silent
|
||||
-print-settings noscale,landscape,fit
|
||||
<pdf_file>
|
||||
```
|
||||
**Problem:** SumatraPDF doesn't communicate page size to printer driver
|
||||
- Printer uses its default paper size setting
|
||||
- If printer is set to "Continuous" or "Roll" mode → prints on long paper
|
||||
- No explicit paper size passed to printer driver
|
||||
|
||||
---
|
||||
|
||||
## 🛠️ Root Cause
|
||||
|
||||
Thermal label printers need EXPLICIT paper size configuration:
|
||||
|
||||
1. **Windows Printing System Issue:**
|
||||
- PDF page size ≠ Printer paper size
|
||||
- Printer driver must be told: "USE THIS EXACT SIZE"
|
||||
- SumatraPDF: Generic PDF viewer, doesn't set printer DEVMODE
|
||||
|
||||
2. **Printer Default Settings:**
|
||||
- Most thermal printers default to continuous roll
|
||||
- Without explicit size, they print entire "page" length
|
||||
- Result: 90cm of paper with label at the end
|
||||

|
||||
|
||||
## ✅ Proposed Solutions
|
||||
|
||||
### **Solution 1: Configure Printer Paper Size (Recommended)**
|
||||
|
||||
#### Manual Configuration:
|
||||
1. Open **Printer Preferences** for "Labels" printer
|
||||
2. Go to **Page Setup** or **Paper/Quality** tab
|
||||
3. Set paper size to **Custom: 35mm x 25mm**
|
||||
4. Set orientation to **Landscape**
|
||||
5. Save as default
|
||||
|
||||
#### PowerShell Script:
|
||||
```powershell
|
||||
# Run the printer configuration script
|
||||
.\configure_label_size.ps1
|
||||
```
|
||||
|
||||
**Pros:**
|
||||
- ✅ One-time setup
|
||||
- ✅ Works with any PDF viewer
|
||||
- ✅ Simplest solution
|
||||
|
||||
**Cons:**
|
||||
- ❌ Needs manual configuration per computer
|
||||
- ❌ Settings can be reset by driver updates
|
||||
|
||||
---
|
||||
|
||||
### **Solution 2: Use Win32 Print API with Explicit Size (Best Control)**
|
||||
|
||||
Use `print_with_size.py` module that:
|
||||
- Opens printer with Win32 API
|
||||
- Sets DEVMODE structure with exact dimensions:
|
||||
```python
|
||||
devmode.PaperSize = 256 # Custom
|
||||
devmode.PaperLength = 250 # 25mm in 0.1mm units
|
||||
devmode.PaperWidth = 350 # 35mm in 0.1mm units
|
||||
devmode.Orientation = 2 # Landscape
|
||||
```
|
||||
- Prints with guaranteed size
|
||||
|
||||
**Implementation:**
|
||||
```python
|
||||
# In print_label.py, replace SumatraPDF call with:
|
||||
from print_with_size import set_printer_paper_size, print_with_custom_size
|
||||
|
||||
# Configure printer once
|
||||
set_printer_paper_size(printer_name, 35, 25)
|
||||
|
||||
# Then print normally
|
||||
print_to_printer(printer_name, pdf_file)
|
||||
```
|
||||
|
||||
**Pros:**
|
||||
- ✅ Programmatic control
|
||||
- ✅ Always sets correct size
|
||||
- ✅ No manual configuration needed
|
||||
|
||||
**Cons:**
|
||||
- ❌ More complex code
|
||||
- ❌ Windows-only
|
||||
- ❌ Requires pywin32
|
||||
|
||||

|
||||
|
||||
### **Solution 3: Use Label Template PDF (Most Reliable)**
|
||||
|
||||
Create a proper label template that printers recognize:
|
||||
|
||||
1. **Design in Label Software:**
|
||||
- Use manufacturer's label design software (e.g., Zebra Designer, BarTender)
|
||||
- Or use professional tool like Adobe Illustrator
|
||||
- Export as PDF with embedded printer settings
|
||||
|
||||
2. **Template Features:**
|
||||
- Embedded page size metadata
|
||||
- Printer-specific settings
|
||||
- Registration marks (optional)
|
||||
|
||||
3. **Dynamic Field Replacement:**
|
||||
- Template has placeholder text: `{COMANDA}`, `{ARTICLE}`, `{SERIAL}`
|
||||
- Python replaces placeholders before printing
|
||||
- Or use PDF form fields
|
||||
|
||||
**Implementation:**
|
||||
```python
|
||||
# Create template with proper settings
|
||||
from PyPDF2 import PdfReader, PdfWriter
|
||||
from reportlab.pdfgen import canvas
|
||||
from reportlab.lib.units import mm
|
||||
|
||||
def fill_label_template(template_path, data, output_path):
|
||||
"""
|
||||
Fill label template with data.
|
||||
Template has proper printer settings embedded.
|
||||
"""
|
||||
# Read template
|
||||
template = PdfReader(template_path)
|
||||
|
||||
# Create overlay with data
|
||||
packet = io.BytesIO()
|
||||
c = canvas.Canvas(packet, pagesize=(35*mm, 25*mm))
|
||||
|
||||
# Add text at specific coordinates
|
||||
c.setFont("Helvetica-Bold", 8)
|
||||
c.drawString(15*mm, 18*mm, f"Nr. Comanda: {data['comanda']}")
|
||||
c.drawString(15*mm, 12*mm, f"Nr. Art.: {data['article']}")
|
||||
c.drawString(15*mm, 6*mm, f"Serial No.: {data['serial']}")
|
||||
c.save()
|
||||
|
||||
# Merge with template
|
||||
overlay = PdfReader(packet)
|
||||
page = template.pages[0]
|
||||
page.merge_page(overlay.pages[0])
|
||||
|
||||
# Write output
|
||||
writer = PdfWriter()
|
||||
writer.add_page(page)
|
||||
|
||||
with open(output_path, 'wb') as f:
|
||||
writer.write(f)
|
||||
|
||||
return output_path
|
||||
```
|
||||
|
||||
**Pros:**
|
||||
- ✅ Most reliable across different systems
|
||||
- ✅ Printer recognizes format immediately
|
||||
- ✅ Professional appearance
|
||||
- ✅ Can include printer-specific optimizations
|
||||
|
||||
**Cons:**
|
||||
- ❌ Requires template creation/design
|
||||
- ❌ Changes need template update

|
||||
|
||||
## 🎓 Why This Happens
|
||||
|
||||
**Technical Explanation:**
|
||||
|
||||
Thermal label printers have two modes:
|
||||
1. **Label Mode:** Prints on predefined label sizes (35mm, 50mm, etc.)
|
||||
2. **Continuous Mode:** Prints on continuous roll (any length)
|
||||
|
||||
When you send a PDF:
|
||||
- PDF says: "I'm 35mm x 25mm"
|
||||
- Printer says: "I don't see a label size command, using default (continuous)"
|
||||
- Result: Prints on continuous roll
|
||||
|
||||
**Solution:** Tell printer explicitly to use Label Mode with 35mm x 25mm size.

# Thermal Printer Paper Size Configuration Guide
|
||||
|
||||
## Problem
|
||||
When printing labels, the PDF is generated correctly at 35mm x 25mm, but SumatraPDF prints them scaled to the printer's currently configured paper size. This results in incorrectly sized labels.
|
||||
|
||||
## Root Cause
|
||||
SumatraPDF's `noscale` mode preserves the PDF content but still uses the **Windows printer's configured paper size**. If the printer is set to A4, Letter, or continuous roll, the label will be scaled to that size.
|
||||
|
||||
## Solution
|
||||
Configure your thermal printer in Windows with the correct paper size (35mm x 25mm).
|
||||
|
||||
---
|
||||
|
||||
## Quick Setup
|
||||
|
||||
### Step 1: Run Configuration Helper
|
||||
```powershell
|
||||
powershell -ExecutionPolicy Bypass -File configure_printer_paper_size.ps1
|
||||
```
|
||||
|
||||
### Step 2: Manual Configuration
|
||||
|
||||
#### For Citizen CTS-310 Printers:
|
||||
1. Open **Control Panel** → **Devices and Printers**
|
||||
2. Right-click **Citizen CTS-310II** → **Printing Preferences**
|
||||
3. Under **Page Layout** or **Paper Settings**:
|
||||
- **Paper Size**: Custom
|
||||
- **Width**: 35mm (1.38 inches)
|
||||
- **Height**: 25mm (0.98 inches)
|
||||
- **Orientation**: Landscape
|
||||
4. Click **Apply** → **OK**
|
||||
|
||||
#### For Zebra ZD420/ZD421 Printers:
|
||||
1. Open **Zebra Setup Utility** (ZSU) or Settings
|
||||
2. Select your printer
|
||||
3. Configure **Media**:
|
||||
- **Media Type**: Label Stock (NOT Continuous)
|
||||
- **Label Width**: 35mm
|
||||
- **Label Height**: 25mm
|
||||
4. Configure **Print Quality**:
|
||||
- **Darkness**: 10-15
|
||||
- **Print Speed**: 4 ips
|
||||
5. **Send to Printer**
|
||||
|
||||
---
|
||||
|
||||
## Critical Settings
|
||||
|
||||
### ⚠️ Media Type MUST be "Labels" or "Label Stock"
|
||||
- **Correct**: Media Type = Labels (enables gap sensor)
|
||||
- **Wrong**: Media Type = Continuous (prints entire roll, ignores gaps)
|
||||
|
||||
### Paper Dimensions
|
||||
- **Width**: 35mm
|
||||
- **Height**: 25mm
|
||||
- **Orientation**: Landscape (35mm is width, 25mm is height)
|
||||
|
||||
### Print Quality (Thermal Printers)
|
||||
- **Darkness**: 10-15 (NOT DPI - thermal printers use darkness control)
|
||||
- **Speed**: Medium (4 ips recommended)
|
||||
- **Resolution**: 203-300 DPI (hardware fixed, not configurable)
|
||||
|
||||
---
|
||||
|
||||
## Verification
|
||||
|
||||
### Test Your Configuration:
|
||||
1. Start the GUI:
|
||||
```bash
|
||||
python label_printer_gui.py
|
||||
```
|
||||
|
||||
2. Add test data to `C:\Users\Public\Documents\check.txt`:
|
||||
```
|
||||
COM-001;ART-123;SN-001;0;1
|
||||
```
|
||||
|
||||
3. Check the printed label:
|
||||
- ✅ Should be exactly 35mm x 25mm
|
||||
- ✅ Should fit the label perfectly (no scaling)
|
||||
- ✅ Should stop at label gap (not continue on roll)
|
||||
|
||||
### If Labels are Wrong Size:
|
||||
- Too large → Printer paper size is too big (check Windows printer settings)
|
||||
- Too small → PDF might be generated incorrectly (check pdf_backup/ folder)
|
||||
- Continuous printing → Media Type is set to "Continuous" instead of "Labels"
|
||||
|
||||
---
|
||||
|
||||
## Windows Custom Paper Size (Advanced)
|
||||
|
||||
If your printer driver doesn't have 35mm x 25mm preset:
|
||||
|
||||
### Create Custom Form:
|
||||
1. Open **Control Panel** → **Devices and Printers**
|
||||
2. Select any printer → **Print Server Properties** (top menu)
|
||||
3. Check **"Create a new form"**
|
||||
4. Form name: **Label35x25**
|
||||
5. Width: **3.50 cm** (35mm)
|
||||
6. Height: **2.50 cm** (25mm)
|
||||
7. Click **Save Form**
|
||||
8. Now this form will be available in all printer settings
|
||||
|
||||
### Assign Form to Printer:
|
||||
1. Right-click your thermal printer → **Printer Properties** (not Preferences)
|
||||
2. **Device Settings** tab
|
||||
3. **Form to Tray Assignment** → Select **Label35x25**
|
||||
4. Apply → OK
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Problem: Labels still wrong size after configuration
|
||||
**Solution**:
|
||||
- Restart the printer
|
||||
- Restart the print spooler: `net stop spooler && net start spooler`
|
||||
- Check if driver supports custom sizes (some old drivers don't)
|
||||
|
||||
### Problem: Printer prints continuously without stopping
|
||||
**Solution**:
|
||||
- Change Media Type from "Continuous" to "Labels"
|
||||
- Enable gap sensor in printer settings
|
||||
- Calibrate media (Zebra: hold feed button 2 seconds)
|
||||
|
||||
### Problem: Dotted or poor quality text
|
||||
**Solution**:
|
||||
- Increase darkness setting (10-15 recommended)
|
||||
- Clean printhead
|
||||
- Check ribbon (thermal transfer) or label quality
|
||||
|
||||

|
||||
|
||||
## File Format (check.txt)
|
||||
|
||||
```
|
||||
ARTICLE;NR_ART;SERIAL;TEMPLATE_TYPE;COUNT
|
||||
```
|
||||
|
||||
Examples:
|
||||
- `COM-001;ART-123;SN-001;0;1` = 1 OK label (green checkmark)
|
||||
- `COM-002;ART-456;SN-002;1;2` = 2 NOK labels (red text + "NOK")
|
||||
|
||||
Template Types:
|
||||
- **0** = OK template (green checkmark, "OK" text)
|
||||
- **1** = NOK template (red text, red checkmark, "NOK" text)
|
||||
|
||||
---
|
||||
|
||||
## Technical Details
|
||||
|
||||
### PDF Generation Pipeline:
|
||||
1. **SVG Template** (conf/label_template_*.svg)
|
||||
- Dimensions: `width="35mm" height="25mm"`
|
||||
- Variables: `{Article}`, `{NrArt}`, `{Serial}`
|
||||
|
||||
2. **CairoSVG Conversion**
|
||||
- Converts SVG → PDF at 300 DPI
|
||||
- Preserves SVG dimensions (35mm x 25mm)
|
||||
|
||||
3. **SumatraPDF Printing**
|
||||
- Uses `-print-settings noscale` (no scaling)
|
||||
- Sends PDF directly to printer
|
||||
- Uses printer's configured paper size
|
||||
|
||||
### Why Paper Size Configuration is Critical:
|
||||
SumatraPDF's `noscale` tells it "don't scale the PDF content", but the **printer driver** still needs to know what paper size to use. If the driver thinks it's printing on A4 paper, it will center the 35mm label on an A4 page.
|
||||
|
||||
By configuring the printer with 35mm x 25mm paper, the driver knows to feed labels of that size, and SumatraPDF will print the PDF content unscaled to match.
|
||||
|
||||

|
||||
|
||||
## Support
|
||||
|
||||
For issues:
|
||||
1. Check printer configuration: `configure_printer_paper_size.ps1`
|
||||
2. Verify PDF dimensions: Open file from `pdf_backup/` in Adobe Reader
|
||||
3. Check logs: `logs/print_log_YYYYMMDD.csv`
|
||||
4. Test with Microsoft Print to PDF first (configure it for 35mm x 25mm)

|
||||
|
||||
## 🔧 Troubleshooting
|
||||
|
||||
### If print quality is still poor:
|
||||
|
||||
1. **Run the printer quality check:**
|
||||
```powershell
|
||||
.\check_printer_quality.ps1
|
||||
```
|
||||
|
||||
2. **Check label material:**
|
||||
- Direct thermal labels need heat-sensitive coating
|
||||
- Thermal transfer labels need ribbon cartridge
|
||||
- Wrong label type = poor quality
|
||||
|
||||
3. **Verify printer driver:**
|
||||
- Update to latest driver from manufacturer's website
|
||||
- Some generic drivers don't support high-quality settings
|
||||
|
||||
4. **Test print from printer:**
|
||||
- Print a self-test page from the printer
|
||||
- This verifies printer hardware is functioning correctly
|
||||
|
||||
5. **Check printhead:**
|
||||
- Dirty printhead = streaky output
|
||||
- Clean printhead with isopropyl alcohol and cleaning cards
|
||||
|
||||
6. **Adjust print darkness:**
|
||||
- Too light: Increase darkness/temperature
|
||||
- Too dark: Decrease darkness/temperature
|
||||
- Adjust in printer preferences or physical dial
|
||||

|
||||
|
||||
## File Structure
|
||||
|
||||
```
|
||||
adaptronic_label-printer/
|
||||
├── label_printer_gui.py # Main GUI application
|
||||
├── print_label.py # Printing logic
|
||||
├── print_label_pdf.py # PDF generation with SVG support
|
||||
├── requirements_gui.txt # Dependencies
|
||||
├── conf/

|
||||
├── logs/ # Print logs
|
||||
└── old_code/ # Legacy scripts (archived)
|
||||
```
|
||||
|
||||
## Customizing Labels
|

|
||||
- `{Article}` - Article/Command number
|
||||
- `{NrArt}` - Article number
|
||||
- `{Serial}` - Serial number
|
||||
|
||||
After editing the SVG, labels will automatically use the new layout.
|
||||
|
||||
## Printing
|
||||
|
||||
### Silent Printing (Recommended)
|
||||
|
||||
Labels print automatically using SumatraPDF. No dialogs or manual steps required.
|
||||
|
||||
**SumatraPDF Locations Checked:**
|
||||
1. Bundled with exe (for deployments)
|
||||
2. `SumatraPDF/` folder in project directory
|
||||
3. System installations (`C:\Program Files\SumatraPDF\`)
|
||||
|
||||
### PDF Printer Testing
|
||||
|
||||
Select "Microsoft Print to PDF" or similar PDF printer to test label generation without physical printing.
|
||||
|
||||
### Printer Configuration
|
||||
|
||||
For thermal printers, configure in Windows Printer Preferences:
|
||||
- **Media Type**: LABELS (enables gap sensor)
|
||||
- **Paper Size**: 35mm x 25mm or Custom
|
||||
- **Orientation**: Landscape
|
||||
- **Darkness**: 10-15 (medium)
|
||||
- **Speed**: Medium (4-6 in/sec)
|
||||
|
||||
## Dependencies
|
||||
|
||||
Core:
|
||||
- `reportlab` - PDF generation
|
||||
- `svglib` - SVG to PDF conversion

||||
|
||||
## Troubleshooting
|
||||
|
||||
### Labels Print on Continuous Roll
|
||||
|
||||
**Cause**: Printer Media Type set to "Continuous" instead of "LABELS"
|
||||
**Fix**: Change to "LABELS" in printer preferences
|
||||
|
||||
### Dotted or Pixelated Text
|
||||
|
||||
**Cause**: Low darkness setting or draft mode
|
||||
**Fix**: Increase darkness to 12-15, ensure quality mode enabled
|
||||
|
||||
### PDF Not Printing Automatically
|
||||
|
||||
**Cause**: SumatraPDF not found
|
||||
**Fix**: Install SumatraPDF or place in project folder
|
||||
|
||||
## Technical Details
|
||||
|
||||
### PDF Generation
|
||||
- **Resolution**: 1200 DPI
|
||||
- **Compression**: None (maximum quality)
|
||||
- **Font Size**: 8pt (optimized for 35mm labels)
|
||||
- **Format**: ReportLab with SVG embedding
|
||||
|
||||
### Print Workflow
|
||||
1. Monitor `C:\Users\Public\Documents\check.txt` for changes
|
||||
2. Parse semicolon-separated data
|
||||
3. Replace variables in SVG template
|
||||
4. Convert to high-quality PDF (35mm × 25mm)
|
||||
5. Auto-save to `pdf_backup/`
|
||||
6. Silent print via SumatraPDF
|
||||
|
||||
## Building Executable
|
||||
|
||||
```powershell
|
||||
python build_exe.py
|
||||

# Simple Label Printer Setup Guide
|
||||
|
||||
## 🎯 The Correct Workflow
|
||||
|
||||
### How It Works:
|
||||
1. **GUI monitors** text file for changes (`C:\Users\Public\Documents\check.txt`)
|
||||
2. **When file changes**, reads data: `COMANDA;NR_ART;SERIAL`
|
||||
3. **Replaces variables** in SVG template (`conf/label_template.svg`):
|
||||
- `{Article}` → COMANDA value
|
||||
- `{NrArt}` → NR_ART value
|
||||
- `{Serial}` → SERIAL value
|
||||
4. **Converts SVG → PDF** at exact 35mm x 25mm size
|
||||
5. **Prints PDF** to configured printer
|
||||
6. **Saves backup** in `pdf_backup/` folder
|
||||
|
||||
### Template Customization:
|
||||
- Edit `conf/label_template.svg` to change label layout
|
||||
- Move text positions, add graphics, change fonts
|
||||
- Keep placeholders: `{Article}`, `{NrArt}`, `{Serial}`
|
||||
- No code changes needed!
|
||||
|
||||

|
||||
|
||||
## 🚀 ONE-TIME Setup (5 Minutes)
|
||||
|
||||
### Step 1: Configure Printer (REQUIRED)
|
||||
```powershell
|
||||
.\setup_printer.ps1
|
||||
```
|
||||
|
||||
**What this does:**
|
||||
- Opens printer preferences dialog
|
||||
- Guides you to set:
|
||||
- Paper Size: **35mm x 25mm** (custom)
|
||||
- Orientation: **Landscape**
|
||||
- Quality: **BEST/600 DPI**
|
||||
- Tests printing
|
||||
|
||||
**This is CRITICAL** - without correct paper size, you'll get:
|
||||
- ❌ 1 meter roll printing
|
||||
- ❌ Wrong label size
|
||||
- ❌ Portrait instead of landscape
|
||||
|
||||

## 🎯 Key Features
|
||||
|
||||
### 1. **Customizable Layout** (SVG Template)
|
||||
- Location: `conf/label_template.svg`
|
||||
- Users can edit this file to change:
|
||||
- Position of text fields
|
||||
- Font size and style
|
||||
- Graphics/images
|
||||
- Label dimensions
|
||||
- **No code changes needed!**
|
||||
|
||||
### 2. **Variable Placeholders**
|
||||
The template uses curly braces for variables:
|
||||
- `{Article}` - First value (Nr. Comanda)
|
||||
- `{NrArt}` - Second value (Nr. Art.)
|
||||
- `{Serial}` - Third value (Serial No.)
|
||||
|
||||
User can move these anywhere in the SVG template.
|
||||
|
||||
### 3. **Automatic File Monitoring**
|
||||
- Watches: The configured txt file
|
||||
- On change: Automatically reads and prints
|
||||
- No manual intervention needed
|
||||

|
||||
|
||||
## 🔧 What Was Fixed
|
||||
|
||||
### Problem 1: SVG Template Was Disabled ❌
|
||||
**Before:** Code was using fallback PDF generation (hardcoded layout)
|
||||
**Now:** SVG template is properly enabled and used
|
||||
|
||||
### Problem 2: Poor SVG Rendering ❌
|
||||
**Before:** svglib was failing with many errors, causing fragmentedoutput
|
||||
**Now:** CairoSVG is used first (better font/rendering support)
|
||||
|
||||
### Problem 3: Extra Conversion Steps ❌
|
||||
**Before:** GhostScript was re-converting already good PDFs
|
||||
**Now:** Direct SVG → PDF → Print (no extra conversions)

## 📝 Data Flow Example
|
||||
|
||||
### Input File Content:
|
||||
```
|
||||
COM-2024-002;ART-67890;SN-20260212
|
||||
```
|
||||
|
||||
### Parsing:
|
||||
```python
|
||||
parts = text.split(';')
|
||||
article = parts[0] # "COM-2024-002"
|
||||
nr_art = parts[1] # "ART-67890"
|
||||
serial = parts[2] # "SN-20260212"
|
||||
```
|
||||
|
||||
### Template Before Replacement:
|
||||
```xml
|
||||
<text>Nr. Comanda:{Article}</text>
|
||||
<text>Nr. Art.:{NrArt}</text>
|
||||
<text>Serial No.:{Serial}</text>
|
||||
```
|
||||
|
||||
### Template After Replacement:
|
||||
```xml
|
||||
<text>Nr. Comanda:COM-2024-002</text>
|
||||
<text>Nr. Art.:ART-67890</text>
|
||||
<text>Serial No.:SN-20260212</text>
|
||||
```
|
||||
|
||||
### Output:
|
||||
- PDF file: `pdf_backup/final_label_20260213_HHMMSS.pdf`
|
||||
- Print: Sent to configured printer
|
||||
- Log: Entry added to `logs/print_log_20260213.csv`
|
||||

|
||||
|
||||
## 🎨 How to Customize the Label Layout
|
||||
|
||||
1. **Open the template:**
|
||||
```
|
||||
conf/label_template.svg
|
||||
```
|
||||
|
||||
2. **Edit in any SVG editor:**
|
||||
- Inkscape (free)
|
||||
- Adobe Illustrator
|
||||
- CorelDRAW
|
||||
- Or any text editor
|
||||
|
||||
3. **Keep the variable placeholders:**
|
||||
- `{Article}`
|
||||
- `{NrArt}`
|
||||
- `{Serial}`
|
||||
|
||||
4. **Save the file**
|
||||
|
||||
5. **Next print will use the new layout!**
|
||||
|
||||
### Example Changes:
|
||||
- Move text to different positions
|
||||
- Change font size in the SVG
|
||||
- Add company logo
|
||||
- Change colors
|
||||
- Adjust spacing
|
||||

## 🚀 Testing the Workflow
|
||||
|
||||
### Test 1: Verify Template is Used
|
||||
```powershell
|
||||
.\venv\Scripts\python.exe label_printer_gui.py
|
||||
```
|
||||
|
||||
Watch console output - should see:
|
||||
```
|
||||
Using SVG template: conf\label_template.svg
|
||||
Converting SVG to PDF using CairoSVG (high quality)...
|
||||
✅ PDF created from SVG template: pdf_backup\final_label_...pdf
|
||||
```
|
||||
|
||||
### Test 2: Check the Generated PDF
|
||||
```powershell
|
||||
# Open latest PDF to verify content
|
||||
$latest = Get-ChildItem pdf_backup\*.pdf | Sort-Object LastWriteTime -Desc | Select-Object -First 1
|
||||
Start-Process $latest.FullName
|
||||
```
|
||||
|
||||
Verify you see:
|
||||
- ✅ Three lines of text (Nr. Comanda, Nr. Art., Serial No.)
|
||||
- ✅ Values filled in correctly
|
||||
- ✅ Checkmark image (if template has it)
|
||||
|
||||
### Test 3: Print Test
|
||||
Put sample data in your monitored file:
|
||||
```
|
||||
COM-TEST-001;ART-7777;SN-20260213
|
||||
```
|
||||
|
||||
Should automatically print with correct values.

||||
## ⚙️ Configuration Files
|
||||
|
||||
### 1. **Label Template** (conf/label_template.svg)
|
||||
- **Purpose:** Defines layout, positions, fonts
|
||||
- **Editable:** Yes - by user
|
||||
- **Format:** SVG (XML-based vector graphics)
|
||||
|
||||
### 2. **App Configuration** (conf/app.conf)
|
||||
- **Purpose:** Stores GUI settings
|
||||
- **Contains:**
|
||||
- File path to monitor
|
||||
- Selected printer
|
||||
- Preview settings
|
||||
|
||||
### 3. **Images** (conf/*.png)
|
||||
- **accepted.png:** Checkmark/approval image (embedded in template)
|
||||
- **refused.png:** Rejection image (if needed)
|
||||
|
||||

|
||||
|
||||
## 🔄 Complete Print Quality Settings
|
||||
|
||||
The system now maintains quality through:
|
||||
|
||||
1. **SVG Template** → Vector graphics (scalable, sharp)
|
||||
2. **CairoSVG Conversion** → Renders @ 1200 DPI
|
||||
3. **PDF Output** → Uncompressed, high quality
|
||||
4. **Printer Configuration** → Set to 600 DPI minimum
|
||||
5. **Direct Printing** → No extra conversions
|
||||

## 🐛 Troubleshooting
|
||||
|
||||
### Issue: "SVG template not found"
|
||||
**Solution:** Check that `conf/label_template.svg` exists
|
||||
|
||||
### Issue: "CairoSVG conversion failed"
|
||||
**Solution:**
|
||||
```powershell
|
||||
.\venv\Scripts\pip.exe install --upgrade cairosvg
|
||||
```
|
||||
|
||||
### Issue: Wrong values printed
|
||||
**Solution:** Verify data format in txt file: `value1;value2;value3`
|
||||
|
||||
### Issue: Printer prints blank/partial
|
||||
**Solution:** Run printer configuration:
|
||||
```powershell
