TM-U220 Technical Reference Guide You don't have to be afraid when you use the printer with OPOS or Advanced Printer Driver (APD) and you set the memory switch as [MemSW 8-5: OFF], [MemSW 8-8: OFF]. Because the status behavior normally doesn't affect your application. When you use the printer with ESC/POS commands (when you control printer without any driver), read the sentences below: The TM-U210 uses the "waiting on-line recover" bit in ASB status (the bit may indicate "0" or "1"); however, the TM-U220 does not use the bit (the bit is always "0"). Because the TM-U220 recovers to online when the cover is closed (cover is closed is detected by the cover open detector.) Therefore, if your application program watches the bit, confirm that it doesn't affect the performing of program. By the way, the ASB data transmitted timing of TM-U220 is same as TM-U210. You don't have to be afraid when your application program doesn't watch the bit. Note: The "waiting on-line recover" is a status which is constructed by a bit in ASB (Auto Status Back) data. The status is for telling that the printer is not prepared to print (roll paper cover isn't closed, etc...) to the host PC. The status tells that the preparation done by the host PC is canceled. This status is canceled by action of the FEED button or host PC. These canceling actions must be executed after the roll paper is installed and roll paper cover is closed. The "waiting on-line recover"bit of TM-U220 is always "0," because the TM-U220 can tell "ready for printing (roll papaer is installed and roll paper cover is closed )" to the host PC. 6.1.7 Use for Journal TM-U220 Type A is able to be used for journal as TM-U210 (Type A.)
