Two sepearte installations of Ubuntu 20.04, one on my pc and one on a friend's both using the same iso. The installations proceeded flawlesly but neither of our multipurpose devices function. They appear in the settings>printer folder but printing fails on both. I suspect a similar issue. My printer is a Canon MP2550 while my friend's is a HP 6978 Officejet. The logs I have from running tests on the Canon are as followsare as follow
