Rev. A Notices for Replacement of the TM-U210/TM-U220/TM-U300 6-15
TM-U220II Technical Reference Guide
6.2.9.2 OPOS
The TM-U220II does not have OPOS compatibility with the TM-U300.
Therefore, the TM-U220II cannot be operated using the TM-U300 OPOS. However, you can
easily replace the printer module in OPOS. You only have to change the printer device of the
TM-U300 to another printer.
See “6.2.1 Printing format compatibility (6-9 page).” for the print margin differences.
6.2.10 ESC/POS command (Direct control)
The TM-U220II has some ESC/POS command compatibility with the TM-U300. See “Printing
format compatibility” (page 6-9) for the print margin differences.
