How to install a Canon PIXMA IP 3300?

After updating to Ubuntu 20.04.1 LTS, I find myself unable to communicate with my Canon PIXMA iP 3300 printer. I have tried several techniques:

1. Adding a PPA supposed to contain drivers for this printer. According to various sources (including https://doc.ubuntu-fr.org/tutoriel/ppa_canon), either ppa:thierry-f/fork-michael-gruz or ppa:michael-gruz/canon-trunk or ppa:michael-gruz/canon-trunk should have it, but it seems to not be the case anymore.

2. Finding the drivers on the various Canon websites (Europe, USA, Asia, canondrivers, etc.) On most of them, I did not find anything for Linux. On Canon Asia, I found a driver for 32-bits RPM-based Linux systems. Conversions with alien, as suggested by some tutorials have proven useless on my 64-bits system.

3. Some other sources (including for instance) contain long and complicated tutorials that usually involve patching together various RPM packages and installing them by hand.

Nothing, in my case, has proven successful. What is a (if possible clean) way to install my Canon PIXMA iP 3300 printer on Ubuntu 20.04?
