My group has inherited a WorkCentre 3220. I tried to set it up with a Windows 8.1 64-bit machine (and a Win7 64-bit machine too.) I first tried to upgrade the firmware (to .105) since the latest drivers say they require it. However, the firmware update via USB simply doesn't see the printer. The built-in Win8 driver for the 3220 is also unable to print.
Is there some additional USB configuration required?
