I’ve got an epson TM-U220B printer, that’s used with restaurant specific software to print orders. printer is supposed to (& normally does) print most things in black & special additions, etc., in red, but recently started printing everything in red! switching ribbons doesn’t help, as it prints right at first & then, print will go to a combination of red & black & eventually to all red. printer is physically about an hour away from me & is a network printer, so I didn’t want to do anything too drastic, like reset to factory settings, if at all possible.
any idea what could be causing this?
