@foone@digipres.club Am I counting 3 passes per line? I’m guessing you’re printing at the highest resolution, which probably has the paper move a very tiny fraction of an inch in-between passes to improve resolution perhaps? (I remember it was common for 9-pin printers to require two passes, for the medium-resolution mode.) (Also, have you gotten to experience how much slower it is to print color graphics on a dot matrix?)
