Actually, it's not so much XP being a problem, as the Okidata printer driver for XP. You will need to "poke around" in the printer properties/settings to see if you can set the default page length to 7 inches. Failing that, you could always buy an inexpensive laser printer and laser checks from your local office supply store. You don't need specially encoded checks with Adagio, as we include the MICR font for printing the bank information.
