HP Deskjet 6940 Terminal Services printing issues

I have read in depth on TechRepublic and elsewhere regarding the HP deskjet 6940 printer running on terminal services. I have a customer that has a windows xp pro workstation with an HP Deskjet 6940 attached locally with USB. My terminal server is a Windows 2003 server. The customer is using quickbooks through the terminal server and printing back to his workstation with the printer on it. I was able to get it working using the 694C driver, but then the formatting of the quickbooks printout is really small and it cuts off half the page. (vertically) I also heard to try the 6980 driver but it is the exact same driver as the 6940 so it won’t work either. Does anyone else have any ideas?
