Hi @johnM

It seems like the printer is recognized but isn’t processing the print jobs. Here are a few steps you can try:

  1. Check Printer Connection and Power
    Ensure that the printer is correctly connected, powered on, and not displaying any error lights or messages.

  2. Install Printer Drivers
    The printer might need proprietary drivers to function correctly. You may want to visit the printer manufacturer’s website to download the most up-to-date drivers compatible with your OS. Canon, for example, provides Linux drivers for many of its printers.

  3. CUPS Configuration
    CUPS (Common Unix Printing System) is used for managing print jobs and queues. Access the CUPS interface by navigating to http://localhost:631/ in a web browser and check the status of the printer and any print jobs.

  4. Printer Settings
    In the printer settings menu, check if the printer is enabled and accepting jobs. If it’s paused or disabled, no jobs will be processed.

  5. Check Print Queue
    If there are any stuck jobs in the print queue, it may prevent new jobs from being processed. Clear the print queue and try again.

  6. Check Ink Levels
    Even if the printer is recognized, if the ink levels are too low, it might not print. Check the ink levels and replace if necessary.

  7. Review Logs
    Check the /var/log/cups/error_log file for any error messages or warnings related to your print jobs, which could give more information on what might be causing the issue.

  8. Command Line
    You can try printing a test page from the command line using a command like lpr -P <printer_name> /usr/share/cups/data/testprint.

After trying these steps, you may have a clearer picture of what might be causing the printing issue on Zorin OS 16.3 Pro.
