Rev. A Notices for Replacement of the TM-U210/TM-U220/TM-U300 6-7

TM-U220II Technical Reference Guide

You don’t have to worry even if you set memory switches 8-5 and 8-8 to OFF when using the

printer with OPOS or Advanced Printer Driver (APD). Status changes normally do not affect

applications.

Read the following if using the printer with ESC/POS commands (if controlling the printer

without the use of drivers).

The TM-U210 uses the “waiting on-line recover” bit in ASB status (“0” or “1” is displayed). The

TM-U220II does not use this bit because it recovers online status when the cover is closed (this is

detected by the cover open detector). Therefore, if your application program monitors that bit,

check that it doesn't affect the program operation.

Note that ASB data transmission timing of the TM-U220II is the same as that of the TM-U210.

You do not have to worry even if your application program does not monitor that bit.

Note:

The “waiting on-line recover” status is configured by an ASB (Auto Status Back) data bit. This status is

for indicating to the host PC that the printer is not prepared to print (roll paper cover isn’t closed, etc.).

This status informs you that the preparation performed by the host PC has been canceled. This status is

canceled by operation of the FEED button or host PC. These canceling operations must be executed after

the roll paper is installed and the roll paper cover is closed.

The “waiting on-line recover” bit of TM-U220II is always “0” because the TM-U220II can indicate to the

host PC that the status is “ready for printing (roll paper is installed and roll paper cover is closed ).”

6.1.7 Use for journal

The TM-U220II TypeA can be used for journals in the same manner as the TM-U210/TM-U220

(Type A). However, you need to be aware of the following points when replacing the TM-U210

with the TM-U220II.

❏ The TM-U210 (Type D) can print two copies using carbon paper but the TM-U220II can only

print one copy using carbon paper.

6.1.8 New functions added (if replacing the TM-U210)

6.1.8.1 Wall hanging

The TM-U220II Type B and D can be installed on a wall using the optional wall-hanging

hardware WH-10.

6.1.8.2 NV bit-image

The TM-U220II can print bit-images on roll paper.

6.1.8.3 User NV memory

The TM-U220II can store text data.
