How to install Canon PIXMA G2010 on Ubuntu 20.10

I followed the instructions at seegatesite.com/driver-printer-canon-pixma-g2010-ubuntu/, but when I try to add the printer at Settings/Printers it says it needs drivers. Is there a better tutorial? Is there an easier method? Google has not been my friend in this effort. This is an installation of 20.10 on a 64GB USB stick, and I am not averse to reformatting the stick and starting over, but I need a printer. Actually I need the Canon Scangear, too. This is a dealbreaker. If I can't install a scanner and printer, I can't use Ubuntu. I could swear I got a printer installed on a version of Ubuntu several years ago, but don't remember anything about how I did it.

Solution 1:

I found the answer at a question about a different Canon printer at AskUbuntu. Sorry, I didn't think to write down the name of the person who gave the answer so I can credit him. Run the command

sudo apt install printer-driver-gutenprint
