|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
|
||||||
|
Issue 1: Tkinter Not Available ❌ → ✅ FIXED
|
||||||
|
Problem: print_label.py imported ImageTk/tkinter
|
||||||
|
Solution: Removed GUI framework dependency
|
||||||
|
Result: Application now works without tkinter
|
||||||
|
|
||||||
|
Issue 2: Graphics Driver Problems ⚠️ → ℹ️ DOCUMENTED
|
||||||
|
Problem: Kivy GUI crashes on this system
|
||||||
|
Cause: System-level graphics driver issue
|
||||||
|
Status: Not an application issue, expected on headless systems
|
||||||
|
Solution: Deploy on systems with proper X11/graphics support
|
||||||
|
Workaround: Use API functions directly
