TM-T81
Specification
(STANDARD)
[Notes] • Frequent write command executions by an NV memory write command may damage
the NV memory. Therefore, it is recommended to write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interface while this command is
being executed, the printer may go into an abnormal condition. Be careful not to
turn the power off or let the printer be reset via an interface while this command is
being executed.
• While processing this command, the printer is BUSY while writing the data to the NV
memory and stops receiving data. Therefore, be sure not to transmit data, including
the real-time commands, while the printer is BUSY.
• When <Function 48, 51, or 64> is transmitted, the data following must not be
transmitted until the status is received. And, it will be necessary to perform the
ESC/POS Handshaking Protocol procedures when using <Function 64>.
<Function 48> GS ( L pL pH m fn (fn = 0, 48)
[Name] Transmit the NV graphics memory capacity
[Format] ASCII GS ( L p
L pH m fn
Hex 1D 28 4C p
L pH m fn
Decimal 29 40 76 p
L pH m fn
[Range] (p
L + pH × 256) = 2 (pL = 2 , pH = 0)
m = 48
fn = 0, 48
[Description] • Transmits the entire capacity of the NV graphics area (number of bytes in the NV
graphics area).
<Function 50> GS ( L pL pH m fn (fn = 2, 50)
[Name] Print the graphics data in the print buffer
[Format] ASCII GS ( L p
L pH m fn
Hex 1D 28 4C p
L pH m fn
Decimal 29 40 76 p
L pH m fn
[Range] (pL + pH × 256) = 2 (pL = 2 , pH = 0)
m = 48
fn = 2, 50
[Description] • Prints the buffered graphics data stored by the process of GS ( L <Function 112>.
