Epson LX-300
I have 2 old Epson LX-300 dot matrix printers, one with colored ribbon prints normally, the other with black ribbon only, with the same parallel cable Centronics and in the same cpu, prints from the center to the right of the sheet and keeps trying to print, would it be an alignment problem or some sensor?
Sometimes she starts printing well but then "slides" to the right of the sheet.
