This may be Windows problem, but maybe someone out there has a clue. I'm using Windows XP-PRO, Arch Desktop 3.3, an HP1050C and an old HP600. I've downloaded and installed the latest HP Designjet drivers for Win XP and eveything is working well with the 1050C. With the HP600 (the driver set for the 1050 includes a driver for the 600) when I do a test print from the WinXP printer setup, all I get is a line of strange symbols down the right side of the roll. Sending a plot file from AutoCAD gets the same result. The built in demo plot on the 600 works fine. Anyone have a suggestion? (short of taking a sledge hammer to the 600 - which I'm tempted to do)
