When Printing 2+ copies of a document, the Xerox prints the square of the copies requested.
When sending to other printers there is no issue.
Suspect corrupted file error in the Xerox driver. (188.8.131.5269)
Just tested on another computer with similar results.
Reinstall the print driver. Preferred V3 driver and not V4 which is known withh some issues.
