Fedora loses connection to printer when resumed from Hibernate/Sleep

Ask Fedora
1

I am printing to a wireless Brother printer model MFC-L2710DW. If I try and print after resuming the system from a sleep or hibernate it can’t locate the printer. However, if I reboot Fedora (33) it manages to find the printer on the network and the printer starts printing the jobs.

There is nothing in the cups log:

Collect the output when the issue happens:

sudo systemctl --no-pager status cups\*; lpstat -t

Also check whether restarting the services helps or not:

sudo systemctl restart cups.service cups.socket cups.path cups-browsed.service

Here is the output of systemctl status:

All looks ok, restarting the services didn’t make any difference. There must be a service that doesn’t get starting or else the wifi comes up after the printer service maybe, not sure…

Try to use another protocol such as AppSocket/JetDirect, IPP or LPD.
