I put a new hard drive and brand new Windows 7 in an old PC and it won't print in color to our network Xerox Phaser 7750 GX printers, including the Windows test page.
The printers are fine and everyone else can print no problem. I've uninstalled, used different printer drivers (the automatically selected & the same as a working PC), tried printer sharing - no joy. The test page print out says color supported: no yet on the PC it says color support is on.
Any ideas?
