you can try running vmware to get a virtual xp mode on the computer. It might work it might not. its better at running programs than device drivers. but its worth a shot
if you give me the exact make and model of the plotter i can see if there are any known work arounds for the issue.
That would be great. i can even log in remotely to help you with it for the same price.
if you accept the additional services offer i can get you my phone number and you can call when its convenient
i will be here all day sunday and monday after noon cst
