■ 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-T88IV, TM-T70, TM-L90, TM-P60, TM-U230,
TM-U220
TM-J2000/J2100
• Printer model ID (n = 1, 49)
Hex = 2BH / Decimal = 43
• Type ID (n = 2, 50)
Bit 1: The bit indicates [Autocutter is installed] always.
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
Program Example for all printers
PRINT #1, CHR$(&H1D);"I";CHR$(1);← Transmits printer ID
