Cannot print after upgrade to Ubuntu 20.04

Hi, I upgraded from 19.10 recently and now I can't print on my Canon mp190 printer. The printer is recognised and I can scan. When I try to print I'm told that the printer is not configured. I have tried reinstalling 20.04 with the printer switched on but no joy. Has anybody shared this experience and, more importantly, found the solution!
Thanks in advance, Spats
