A customer asking me which paper roll is adapted to the printer have I sold : Epson TM-U220B 2-color autocut impact printer with ethernet interface: charcoal
The paper roll needs to have paper compatible with the printer. They want "double printing" paper (duplication). Do you know where the customer could buy that / order that?
The TM-U220B takes standard 72cm (3inch) 2-ply paper rolls. These are generally available at office supply stores.
