Hello Ed at Answers forum,
Thank you for using Microsoft Windows Vista Forums.
I would like to verify some information to assist with this matter. You have a computer with Windows Vista and you are using remote desktop into a computer using Windows XP. Your computer running XP is this connected directly to the printer? Are you able to print from your computer using XP successfully?
Is your printer connected using USB or Parallel Port? Also do you have the drivers for the printer installed on your Vista machine? Please let me know some more information.
