Resuming A CUPS Printer That is Paused or Stopped
If the CUPS printing system has encountered an error with a printer, the printer is usually in stopped or paused state afterwards.
Resuming the printer can be done from the command line or from the CUPS web interface, but sufficient permissions are required anyway.
Resuming a Printer From the Command Line
On the command line, type (e.g. as root):
cupsenable myprinter
to enable the print queue and printer. Replace myprinter from the example here
by the real name of your printer.
Configuring a Printer From the CUPS Web Interface
Open the CUPS web interface in a browser and go to the Printers page:
From the list of queue names, select the printer you want to modify.
Resuming the Printer From the Web Interface
Assuming you have opened the web page associated with your printer.
From selection box Maintenance, select Resume Printer
Alternatively, the printer can be configured to automatically resume after an error. See below.
Automatically Restart the Printer After an Error
Assuming you have opened the web page associated with your printer.
From selection box Administration, select Set Default Options
The page that appears shows e.g. General - Banners - Policies, click on Policies
In the Error Policy: selection field, select e.g. retry-printer instead of stop-printer
Click on the button Set Default Options
The changed setting is saved in configuration file /etc/cups/printers.conf
