If nothing else works, what HAS worked for me in the past is to install the printer to EACH PC, one at a time, connected to the USB port. What this does, is copy proper
drivers to that PC.
Then when you go to Reinstall the printer as a networked device, since each PC already has the drivers installed, if it works for you like it did for me, it won't even prompt you for the drivers; instead, it will just reuse them.
