This script collects data from networked Canon printers and performs the following functions:

1. Connects to MF450 Series and iR2630 printers via URL list

2. Authenticates using preset credentials

3. Gathers data:

   • Device name and serial number
   • Total B&W page count
   • Scanned pages count
   • Printed pages count
   • Toner levels (black, cyan, magenta, yellow)

4. Saves data to CSV file (printer_counters_YYYYMMDD.csv)

5. Maintains operation log (printer_scraper.log) recording successful connections and errors

Additionally, two troubleshooting scripts are included:

• Credential combination testing script
• Model-specific handlers for different printer authentication methods

Logs show some printers are unreachable or have authentication issues, documented in troubleshooting.log.
