• 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
