I have Zorin OS Lite 15.3. When I first installed the OS, my printer-scanner worked immediately after install. Now, months later, something happened and I cannot print. Under Printers, it says "Printing service not available. Start the service on this computer or connect to another server." I found some instructions online to restart the CUPS printing service, but it hasn't fixed the problem. (FYI, the scanner still works fine.)
Any tips on how to get the printing service working again?
