imagePROGRAF PRO-300 Drivers for macOS Monterey

[ingineering]

I just bought a imagePROGRAF PRO-300 to use with my M1 iMac running Monterey. The advanced settings (Quality and Media, Color options, etc.) don't show up in the Print dialog. I installed a printer driver from the Canon site, but that made no difference. The driver download page doesn't list Monterey in the OS versions list. Does this printer actually work properly with Monterey? If so what do I need to do?

This is what I downloaded:

I followed this but I still don't see the paper options. My driver version is 24.20.0.0.

Ha, after restarting the computer the driver works! The 'ol restart trick.
