C2LInspecz is the official diagnostic and health-monitoring utility by Code2Lab. It is a modern, high-performance GUI application designed to identify, troubleshoot, and resolve issues within the Smartsales POS ecosystem.

🚀 Core Features

1. Automated System Audit

A comprehensive "One-Click" audit that analyzes your shop's infrastructure in real-time:

Network Integrity: Verifies LAN connectivity, Internet access, and Shop Server reachability.
Printer Ecosystem:
- USB Printers (Cashier): Scans the physical USB bus to ensure local receipt printers are connected.
- Network Printers (Kitchen/Bar): Pings remote printers to verify they are online and responding.
Hardware Health: Monitors CPU load, RAM usage, and real-time Disk space.

2. The "Spooler Shield" & CUPS Watchdog

The tool actively monitors the printing subsystem to prevent shop downtime:

Queue Monitoring: Detects "Stuck" jobs for both Local USB and Network printers.
Service Monitoring: Real-time status check of the Linux CUPS service.
One-Click Recovery: Purges jammed queues and restarts the print services instantly to restore operations.

3. Active Self-Healing (Storage)

To prevent system crashes due to full storage, C2LInspecz includes an automatic maintenance engine:

Disk Pressure Detection: Triggers when available disk space drops below 2GB.
Temp Cleanup: Automatically purges old PDF reports and temporary files to free up critical system space.

4. Integrated Settings Wizard

No more manual JSON editing. Shop managers can use the ⚙️ Settings tab directly in the app to:

Update the Shop Server IP.
Add, Edit, or Remove Network and USB printers.
Save configurations instantly to the system path.

5. Smart Escalation

Guides users through self-repair (e.g., "Check power cable"). If a failure is unresolvable locally, the tool packages diagnostic logs into a support ticket for the Code2Lab team.
