All I can suggest, is to return to the printer manufacturer's home page and make sure you have downloaded and installed their most up to date printer driver for using their printer under Windows XP. Make sure that the Windows printer driver specifies a 7 inch form as its default. Print a one line page from notepad to make sure the setting is correct.

Make sure that this printer is set as the default printer for the workstation. make sure that the specification has "custom form" and a seven inch page depth. If this doesn't work, then you'll have to call in your local business partner.

Sorry.
