PIXMA PRO-100 colors off, driver reinstallation not helping

[cmpentecost]

I have two Pixma Pro 100 printers. The first one started printing with the colors "off". I'd remove the printer and add it back and it would work for awhile, and then just completely quit printing accurately. Then, the 2nd printer did the same thing. I was printing holiday cards. The first card printed with the correct colors, and the 2nd one was off. I've removed the printers via System Settings > Printers, and then deleted the Canon drivers, unplugged my USB cords from the printers, and reinstalled the drivers. Also, when I turned my printer on and plugged in the USB port, the printer just showed back up in my list of printer, with no actual "installation of choosing my driver". Prior to Ventura, I could see all of this. 

The colors are still off. I don't think I have the right printer driver. With Ventura 13.6.1, I can't tell if I'm using the AirPrint or the Canon driver. All I see is driver 16.80.0.0. I'm at a loss and hope someone can help me out! TIA.

I Googled this, and this step will indeed delete all printers on my computer. With the holidays (and recovering from hand surgery), I will probably wait until after Christmas to try this. I will be sure to post the results. Thank you for this. This step is something I had been totally unaware of.

Something I read elsewhere: in Options & Supplies->General verify that a software update didn't select Use Generic Printer option.

I finally tackled the printer issue today, and tried jrhoffman75's suggestion of control clicking on the printer. I then went into my Mac computer and deleted everything I could for the Canon printer, and then reinstalled the drivers. It seems to have fixed the problem. I've just printed a few things and the colors were accurate again. I'll try it again tomorrow or Saturday and make sure. Thanks jrhoffman75 for your help!

thank you for your suggestion.

I have been printing on a Canon PRO-100S on Canon paper from LR Classic with excellent results... until "something" happened, possibly to the drivers but perhaps to the printer. see attachments below: standard Fuji test image and a snapshot of the best test print of it I could produce (you will have to trust that the shot reflects the actual printed colours).

I have been following the thread and tried resetting the entire print system. Sadly no improvements.

Setup:

Canon PRO-100S  with  16.80.0.0 MacOS driver 

Mac OS 14.2.1 (Sonoma)

Lighroom Classic 13.2. (but same results using Canon apps like Image Garden etc)

Any other ideas please??

For context: I routinely print from LightRoom Classic.  The entire printing workflow is fine-tuned, incl softproofing using the correct paper-specific Canon colour profiles for the printer and the paper I use (eg Canon Pro Luster), setting colour management in LR to the same colour profiles , matching printer setup to the LR printing setup: colour matching correctly disables (as it's handled by LR), media type correctly set for the target paper, etc. nothing has changed, but the results are now very different -- and frustrating.

Please run a nozzle check to be sure all colors are printing correctly.

deep cleaning seems to have done the trick!
