My boss has Quickbooks '99 (old yes, he won't upgrade). His os is xp, he uses quickbooks to print checks. We are having lot's of trouble finding a compatable printer as several have failed. Have tried both serial and usb printers. HP printers did not work at all. His current one is a Brother and it's starting to die, I need a Replacement, any suggestions would be greatly appreciated. Been searching Google with no luck in finding any answers.
