i dont think the driver is supported anymore for mac os 10.7
maybe you can try to use a ppd from an updated machine like the 5635 ot 5735 , those machines are the follow ups from your controller
I am trying to setup my Macbook Pro to use our office Workcenter Pro 255 that is setup up on our network. I downloaded the driver WCP232_UBPD_1.1.1.dmg from Xerox and installed it. Once that was done I setup the IP and noticed that there wasn't any reference to the accounting. We use a 4 digit code for our accounting id. I tried sending a print job to the copier and the result was it printed a report stating that I was an unauthorized user. Is there a different driver I need for my Mac or did I miss something? I am using Mac OS X 10.7.2
