Solution for WorkCentre 3225 and 10.15 Catalina Driver
Product Name: WorkCentre 3225
Operating System: macOS 10.15 Catalina
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.
