I need to control which trays to use for each layout on our Nuvera 288 (for splitting a job with colored paper). But i cant get it to work - it prints the whole job from the same tray instead.

I guess it might be because of the following warning:
"The current printer uses a Xerox User Interface driver. For greatly improved performance, download a generic PPD from http://www.support.xerox.com and run the Adobe Universal PS Driver Installer."

I cant seem to find such a driver? Can someone point me in the right direction?

Note that Adobe hasn't updated this driver in a long time. It won't work on Windows 7.

It's just a warning about performance, though. I doubt it'll help with tray switching.

And i never answered back. Actually the trayswitching WAS dependable of the (old) universal driver and some meddling.
