in a terminal window, with "<printer>" replaced by the name of your print queue (print queue names are shown by the "lpstat -v" command. Then remove all stuck jobs from the print queue and turn off and turn on the printer. Does the problem go away now?
Can you run the command
lpadmin -p <printer> -o usb-unidir- default= true

If not, try the command
lpadmin -p <printer> -o usb-no- reattach- default= true
clear the print queue and power-cycle the printer. Does it work now? If yes, try to remove the first workaround via
lpadmin -p <printer> -R usb-unidir-default
Does it still work?
To remove also the other workaround run
lpadmin -p <printer> -R usb-no- reattach- default
Please post also the output of the command

This way we get the USB IDs of the printer to be able to add permanent exception rules to the CUPS USB backend.
