Epson U220B - TM Two-color Dot-matrix Printer Technical Reference Guide

6-8 Notices for Replacement of the TM-U210/TM-U300 Rev. D
6.1.8.4 Memory Switch and memory switch setup mode
The TM-U220 has a Memory switch which is a software DIP switch. The memory switch setup
mode is for adjusting the memory switches by printer only (No host PC needed.) See “3.4.3
Memory Switches (3-19 page)” and “3.4.4 Memory Switch Setup Mode (3-21 page)” for detail.
6.1.9 Driver compatibility
This section informs you the compatibility and notices for replacing.
6.1.9.1 Advanced Printer Driver
The TM-U220 has compatibility with the TM-U210 in APD. Therefore, the TM-U210 Advanced
Printer Driver can drive the TM-U220. However, the print margin is little different from the
original output, and the TM-U210 driver can’t use NV memory functions. See “6.1.1 About
printing format compatibility (6-1 page)” and “6.1.8 New functions added (6-7 page)” for the
differences.
6.1.9.2 OPOS
TM-U220 has compatibility with the TM-U210 in OPOS. Therefore, the TM-U210 OPOS can
drive the TM-U220. However, the print margin is a little different from the original output, and
the TM-U210 driver can’t use NV memory functions. See “6.1.1 About printing format
compatibility (6-1 page)” and “6.1.8 New functions added (6-7 page)” for the differences.
6.1.9.3 ESC/POS command (Direct control)
The TM-U220 has compatibility with the TM-U210 in ESC/POS commands. Therefore, a
program source for the TM-U210 can drive the TM-U220. However, the print margin is a little
different from original output. See “6.1.1 About printing format compatibility (6-1 page)” for the
difference.
6.2 For Replacement of the TM-U300
6.2.1 About Printing format compatibility
The TM-U220 can print almost the same printing result as the TM-U210/TM-U300. This section
describes the reasons which are printing area compatibility, character compatibility, and top
margin compatibility (cutting position.)
