When using parallel interface, the Bit 2 is fixed to 0 “DM-D (Customer display) is not connected.“
When communication with the printer uses XON/XOFF control, the XOFF code may interrupt the “Header
to NUL” data string.
The printer information A can be differentiated by the header of the block data from other transmission
data. After outputting GS I, if the header transmitted from the printer is [Hex = 3DH/Decimal = 61], data is
processed up to NUL [Hex = 00H/Decimal = 0] as the data block, according to the header and identifier.
[Notes for printer information B]
Each printer information is composed of [header to NUL] (when 65
n
69,
or
n
= 112).
If the printer information is not prepared, [Header + NUL] (2 bytes) are sent.
The firmware version can be confirmed by self test printing. The self test is executed by executing GS ( A,
or by panel switch operation when power is turned on.
With serial interface, when communication with the printer uses XON/XOFF control, the XOFF code may
interrupt the “Header to NUL” data string.
Printer information can be identified to other transmission data according to specific data of the
transmission data block. When the header transmitted by the printer is [hex = 5FH/decimal =95], treat NUL
[hex = 00H/decimal =0] as a data group and identify it according to the following data.
[Model-dependent variations] TM-J2000/J2100, TM-T90, TM-T88III, TM-L90, TM-L60II, TM-P60, TM-U230,
TM-U210, TM-U220
Send data Hex Decimal Data
Header 5FH 95 1 byte
Printer information B Depends on the model Depends on the model 0 to 80 bytes
NUL 00H 0 1 byte
