My Canon MX310 IJ printer and Mohave 14.6 are not compatible

No. It took me to the same Canon website I was using: usa.canon.com.

Here's another thought: I have the same printer driver on my Windows 10 PC, but doubt it would work on a Mac after having been installed on a PC. Whatta ya think?

Canon's response to my request to download a printer driver for my Mac is:

"There is no driver for the OS Version (macOS Mojave v10,14) you selected. The driver may be included in your OS or you may not need a driver."

I think it's pretty obvious the driver is NOT included in this OS and YES I do need a driver, so I guess I should either uninstall Mojave or buy a new printer, huh?

I'm afraid to install the Mac-UFRII LT-CARP(etc, etc) because the recommendation came from Canon UK and because the recommended printers are all Canon I-SENSYS models.

So-o-o-o any suggestions on how to best uninstall Mojave, because I did not make a backup before installing it!

Thank you very much for any help you can offer me at this moment. I really need my printer in order to copy bank statements in order to get a $600 refund of my 2019 Medicare payments.

I had an older version that I've been using for several years, but since I installed Mojave, it just stopped working. I've since deleted it after unsuccessfully resetting the printing system to see if that would work, but I'll now try downloading the same driver I was using before to see if it works. Letcha know!

Well, the Canon website will not let me download an older driver because it senses that my OS is Mojave 10.14. I tried resetting the OS to just 10.14 but that didn't work either. Do you know of a site where I could get an older version of MX310?
