+# Windows Print Service Network Configuration Guide
+
+## Current Issue
+Your Flask server (Linux) cannot connect to Windows Print Service because they're on different machines.
+
+## Solution Options
+
+### Option 1: Same Machine Setup
+If both Flask and Windows service are on the same machine:
+```python
+WINDOWS_PRINT_SERVICE_URL = "http://localhost:8765"
+```
+
+### Option 2: Different Machines (Recommended)
+If Flask server (Linux) and Windows service are on different machines:
+
+1. **Find Windows Machine IP Address:**
+   ```cmd
+   # On Windows machine, run:
+   ipconfig
+   # Look for IPv4 Address, e.g., 192.168.1.100
+   ```
+
+2. **Update Configuration:**
+   ```python
+   # In /app/print_config.py, change:
+   WINDOWS_PRINT_SERVICE_URL = "http://192.168.1.100:8765"
+   ```
+
+3. **Test Connection:**
+   ```bash
+   # From Linux machine, test:
+   curl http://192.168.1.100:8765/health
+   ```
+
+### Option 3: Windows Firewall Configuration
+Ensure Windows allows incoming connections on port 8765:
+
+1. **Windows Firewall Settings:**
+   - Control Panel → System and Security → Windows Defender Firewall
+   - Advanced Settings → Inbound Rules → New Rule
+   - Port → TCP → 8765 → Allow the connection
+
+2. **Test from Linux:**
+   ```bash
+   telnet [WINDOWS_IP] 8765
+   ```
+
+### Option 4: Port Forwarding/Tunneling
+If direct connection isn't possible, set up SSH tunnel or port forwarding.
+
+## Quick Fix for Testing
+
+1. **Get Windows IP Address**
+2. **Update print_config.py with the IP**
+3. **Restart Flask server**
+4. **Test printing**
+
+## Current Status
+- ✅ Windows Print Service: Running (localhost:8765/health works)
+- ❌ Network Connection: Flask can't reach Windows service
+- 🔧 Fix Needed: Update WINDOWS_PRINT_SERVICE_URL with correct IP
+
+## Example Commands
+
+```bash
+# 1. Find Windows IP (run on Windows):
+# ipconfig | findstr IPv4
+
+# 2. Test connection (run on Linux):
+# curl http://[WINDOWS_IP]:8765/health
+
+# 3. Update config and restart Flask
+```
