While the WorkCentre 3225 driver IS NOT Catalina compliant, I noted that the WorkCentre 3335 driver IS Catalina compliant.
I took a chance, downloaded the 3335 driver and installed it.
It works to print to the WorkCentre 3225. At least on my computer it works.
I used a Windows 10 machine to update the firmware on the 3225 as well, and I updated the firmware BEFORE I installed the driver. For some reason, the firmare update wizard did not appear on the Mac, but did on the WIndows machine.
Good luck!
Hi jplattet,
Thank you for providing this information on how yo got your printer to print with the Catalina 10.15. I am sure it will help others with the same issue.
