I performed a "do-release-upgrade" a few days ago from 16.04 LTS to 18.04 LTS. After the upgrade I wasn't able to print. Printing worked before the upgrade.
Printer: Brother MFC-J625DW (connected via WiFi with static IP address 10.0.0.3) Computer: Lenovo ThinkPad T410 (connected to same network as printer; pinged for confirmation)
When I print a test page, the system notifies me that the job was submitted and completed, but the printer doesn't do anything.
I have looked through logs, but I don't really know which messages are pertinent to the situation.
I've managed to fix this problem with past upgrades, but I'm stumped by this one. Any ideas?
