+# CSS Modular Structure Guide
+
+## Overview
+This guide explains how to migrate from a monolithic CSS file to a modular CSS structure for better maintainability and organization.
+
+## New CSS Structure
+
+```
+app/static/css/
+├── base.css          # Global styles, header, buttons, theme
+├── login.css         # Login page specific styles
+├── dashboard.css     # Dashboard and module cards
+├── warehouse.css     # Warehouse module styles
+├── etichete.css      # Labels/etiquette module styles (to be created)
+├── quality.css       # Quality module styles (to be created)
+└── scan.css          # Scan module styles (to be created)
+```
+
+## Implementation Strategy
+
+### Phase 1: Setup Modular Structure ✅
+- [x] Created `css/` directory
+- [x] Created `base.css` with global styles
+- [x] Created `login.css` for login page
+- [x] Created `warehouse.css` for warehouse module
+- [x] Updated `base.html` to include modular CSS
+- [x] Updated `login.html` to use new structure
+
+### Phase 2: Migration Plan (Next Steps)
+
+1. **Extract module-specific styles from style.css:**
+   - Etiquette/Labels module → `etichete.css`
+   - Quality module → `quality.css`
+   - Scan module → `scan.css`
+
+2. **Update templates to use modular CSS:**
+   ```html
+   {% block head %}
+   <link rel="stylesheet" href="{{ url_for('static', filename='css/module-name.css') }}">
+   {% endblock %}
+   ```
+
+3. **Clean up original style.css:**
+   - Remove extracted styles
+   - Keep only legacy/common styles temporarily
+   - Eventually eliminate when all modules migrated
+
+## Template Usage Pattern
+
+### Standard Template Structure:
+```html
+{% extends "base.html" %}
+{% block title %}Page Title{% endblock %}
+
+{% block head %}
+<!-- Include module-specific CSS -->
+<link rel="stylesheet" href="{{ url_for('static', filename='css/module-name.css') }}">
+<!-- Page-specific overrides -->
+<style>
+/* Only use this for page-specific customizations */
+</style>
+{% endblock %}
+
+{% block content %}
+<!-- Page content -->
+{% endblock %}
+```
+
+## CSS Loading Order
+
+1. `base.css` - Global styles, header, buttons, theme
+2. `style.css` - Legacy styles (temporary, for backward compatibility)
+3. Module-specific CSS (e.g., `warehouse.css`)
+4. Inline `<style>` blocks for page-specific overrides
+
+## Benefits of This Structure
+
+### 1. **Maintainability**
+- Easy to find and edit module-specific styles
+- Reduced conflicts between different modules
+- Clear separation of concerns
+
+### 2. **Performance**
+- Only load CSS needed for specific pages
+- Smaller file sizes per page
+- Better caching (module CSS rarely changes)
+
+### 3. **Team Development**
+- Different developers can work on different modules
+- Less merge conflicts in CSS files
+- Clear ownership of styles
+
+### 4. **Scalability**
+- Easy to add new modules
+- Simple to deprecate old styles
+- Clear migration path
+
+## Migration Checklist
+
+### For Each Template:
+- [ ] Identify module/page type
+- [ ] Extract relevant styles to module CSS file
+- [ ] Update template to include module CSS
+- [ ] Test styling works correctly
+- [ ] Remove old styles from style.css
+
+### Current Status:
+- [x] Login page - Fully migrated
+- [x] Warehouse module - Partially migrated (create_locations.html updated)
+- [ ] Dashboard - CSS created, templates need updating
+- [ ] Etiquette module - Needs CSS extraction
+- [ ] Quality module - Needs CSS extraction
+- [ ] Scan module - Needs CSS extraction
+
+## Example: Migrating a Template
+
+### Before:
+```html
+{% block head %}
+<style>
+.my-module-specific-class {
+    /* styles here */
+}
+</style>
+{% endblock %}
+```
+
+### After:
+1. Move styles to `css/module-name.css`
+2. Update template:
+```html
+{% block head %}
+<link rel="stylesheet" href="{{ url_for('static', filename='css/module-name.css') }}">
+{% endblock %}
+```
+
+## Best Practices
+
+1. **Use semantic naming:** `warehouse.css`, `login.css`, not `page1.css`
+2. **Keep base.css minimal:** Only truly global styles
+3. **Avoid deep nesting:** Keep CSS selectors simple
+4. **Use consistent naming:** Follow existing patterns
+5. **Document changes:** Update this guide when adding new modules
+
+## Next Steps
+
+1. Extract etiquette module styles to `etichete.css`
+2. Update all etiquette templates to use new CSS
+3. Extract quality module styles to `quality.css`
+4. Extract scan module styles to `scan.css`
+5. Gradually remove migrated styles from `style.css`
+6. Eventually remove `style.css` dependency from `base.html`

+# Enhanced Print Controller - Features & Usage
+
+## Overview
+The print module now includes an advanced Print Controller with real-time monitoring, error detection, pause/resume functionality, and automatic reprint capabilities for handling printer issues like paper jams or running out of paper.
+
+## Key Features
+
+### 1. **Real-Time Progress Modal**
+- Visual progress bar showing percentage completion
+- Live counter showing "X / Y" labels printed
+- Status messages updating in real-time
+- Detailed event log with timestamps
+
+### 2. **Print Status Log**
+- Timestamped entries for all print events
+- Color-coded status messages:
+  - **Green**: Successful operations
+  - **Yellow**: Warnings and paused states
+  - **Red**: Errors and failures
+- Auto-scrolling to show latest events
+- Scrollable history of all print activities
+
+### 3. **Control Buttons**
+
+#### **⏸️ Pause Button**
+- Pauses printing between labels
+- Useful for:
+  - Checking printer paper level
+  - Inspecting print quality
+  - Loading more paper
+- Progress bar turns yellow when paused
+
+#### **▶️ Resume Button**
+- Resumes printing from where it was paused
+- Appears when print job is paused
+- Progress bar returns to normal green
+
+#### **🔄 Reprint Last Button**
+- Available after each successful print
+- Reprints the last completed label
+- Useful when:
+  - Label came out damaged
+  - Print quality was poor
+  - Label fell on the floor
+
+#### **❌ Cancel Button**
+- Stops the entire print job
+- Shows how many labels were completed
+- Progress bar turns red
+- Database not updated on cancellation
+
+### 4. **Automatic Error Detection**
+- Detects when a label fails to print
+- Automatically pauses the job
+- Shows error message in log
+- Progress bar turns red
+- Prompts user to check printer
+
+### 5. **Automatic Recovery**
+When a print error occurs:
+1. Job pauses automatically
+2. Error is logged with timestamp
+3. User checks and fixes printer issue (refill paper, clear jam)
+4. User clicks "Resume"
+5. Failed label is automatically retried
+6. If retry succeeds, continues with next label
+7. If retry fails, user can cancel or try again
+
+### 6. **Smart Print Management**
+- Tracks current label being printed
+- Remembers last successfully printed label
+- Maintains list of failed labels
+- Prevents duplicate printing
+- Sequential label numbering (CP00000777/001, 002, 003...)
+
+## Usage Instructions
+
+### Normal Printing Workflow
+
+1. **Start Print Job**
+   - Select an order from the table
+   - Click "Print Label (QZ Tray)" button
+   - Print Controller modal appears
+
+2. **Monitor Progress**
+   - Watch progress bar fill (green)
+   - Check "X / Y" counter
+   - Read status messages
+   - View timestamped log entries
+
+3. **Completion**
+   - All labels print successfully
+   - Database updates automatically
+   - Table refreshes to show new status
+   - Modal closes automatically
+   - Success notification appears
+
+### Handling Paper Running Out Mid-Print
+
+**Scenario**: Printing 20 labels, paper runs out after label 12
+
+1. **Detection**
+   - Label 13 fails to print
+   - Controller detects error
+   - Job pauses automatically
+   - Progress bar turns red
+   - Log shows: "✗ Label 13 failed: Print error"
+   - Status: "⚠️ ERROR - Check printer (paper jam/out of paper)"
+
+2. **User Action**
+   - Check printer
+   - See paper is empty
+   - Load new paper roll
+   - Ensure paper is feeding correctly
+
+3. **Resume Printing**
+   - Click "▶️ Resume" button
+   - Controller automatically retries label 13
+   - Log shows: "Retrying label 13..."
+   - If successful: "✓ Label 13 printed successfully (retry)"
+   - Continues with labels 14-20
+   - Job completes normally
+
+### Handling Print Quality Issues
+
+**Scenario**: Label 5 of 10 prints too light
+
+1. **During Print**
+   - Wait for label 5 to complete
+   - "🔄 Reprint Last" button appears
+   - Click button
+   - Label 5 reprints with current settings
+
+2. **Adjust & Continue**
+   - Adjust printer darkness setting
+   - Click "▶️ Resume" if paused
+   - Continue printing labels 6-10
+
+### Manual Pause for Inspection
+
+**Scenario**: Want to check label quality mid-batch
+
+1. Click "⏸️ Pause" button
+2. Progress bar turns yellow
+3. Remove and inspect last printed label
+4. If good: Click "▶️ Resume"
+5. If bad: 
+   - Click "🔄 Reprint Last"
+   - Adjust printer settings
+   - Click "▶️ Resume"
+
+### Emergency Cancellation
+
+**Scenario**: Wrong order selected or major printer malfunction
+
+1. Click "❌ Cancel" button
+2. Printing stops immediately
+3. Log shows labels completed (e.g., "7 of 25")
+4. Progress bar turns red
+5. Modal stays open for 2 seconds
+6. Warning notification appears
+7. Database NOT updated
+8. Can reprint the order later
+
+## Technical Implementation
+
+### Print Controller State
+```javascript
+{
+    isPaused: false,           // Whether job is paused
+    isCancelled: false,        // Whether job is cancelled
+    currentLabel: 0,           // Current label number being printed
+    totalLabels: 0,            // Total labels in job
+    lastPrintedLabel: 0,       // Last successfully printed label
+    failedLabels: [],          // Array of failed label numbers
+    orderData: null,           // Order information
+    printerName: null          // Selected printer name
+}
+```
+
+### Event Log Format
+```
+[17:47:15] Starting print job: 10 labels
+[17:47:15] Printer: Thermal Printer A
+[17:47:15] Order: CP00000777
+[17:47:16] Sending label 1 to printer...
+[17:47:16] ✓ Label 1 printed successfully
+```
+
+### Error Detection
+- Try/catch around each print operation
+- Errors trigger automatic pause
+- Failed label number recorded
+- Automatic retry on resume
+
+### Progress Calculation
+```javascript
+percentage = (currentLabel / totalLabels) * 100
+```
+
+### Color States
+- **Green**: Normal printing
+- **Yellow**: Paused (manual or automatic)
+- **Red**: Error or cancelled
+
+## Benefits
+
+1. ✅ **Prevents Wasted Labels**: Automatic recovery from errors
+2. ✅ **Reduces Operator Stress**: Clear status and easy controls
+3. ✅ **Handles Paper Depletion**: Auto-pause and retry on paper out
+4. ✅ **Quality Control**: Easy reprint of damaged labels
+5. ✅ **Transparency**: Full log of all print activities
+6. ✅ **Flexibility**: Pause anytime for inspection
+7. ✅ **Safety**: Cancel button for emergencies
+8. ✅ **Accuracy**: Sequential numbering maintained even with errors
+
+## Common Scenarios Handled
+
+| Issue | Detection | Solution |
+|-------|-----------|----------|
+| Paper runs out | Print error on next label | Auto-pause, user refills, resume |
+| Paper jam | Print error detected | Auto-pause, user clears jam, resume |
+| Poor print quality | Visual inspection | Reprint last label |
+| Wrong order selected | User realizes mid-print | Cancel job |
+| Need to inspect labels | User decision | Pause, inspect, resume |
+| Label falls on floor | Visual observation | Reprint last label |
+| Printer offline | Print error | Auto-pause, user fixes, resume |
+
+## Future Enhancements (Possible)
+
+- Printer status monitoring (paper level, online/offline)
+- Print queue for multiple orders
+- Estimated time remaining
+- Sound notifications on completion
+- Email/SMS alerts for long jobs
+- Print history logging to database
+- Batch printing multiple orders
+- Automatic printer reconnection
+
+## Testing Recommendations
+
+1. **Normal Job**: Print 5-10 labels, verify all complete
+2. **Paper Depletion**: Remove paper mid-job, verify auto-pause and recovery
+3. **Pause/Resume**: Manually pause mid-job, wait, resume
+4. **Reprint**: Print job, reprint last label multiple times
+5. **Cancel**: Start job, cancel after 2-3 labels
+6. **Error Recovery**: Simulate error, verify automatic retry
+
+## Browser Compatibility
