TM-T81 Specification (STANDARD)
[Notes] • Frequent write command ex ecutions by an NV memory write command m ay damage
the NV memory. Therefore, it is recomm ended t o write to the NV memory less than
10 times a day.
• If the power is turned off or the printer is reset via an interf ace while this command is
being executed, the printer may go int o an abnor m al condition. Be careful not to
turn the power off or let the printer be reset v ia an interface while this com m and is
being executed.
• While processing thi s com mand, the printer is BUSY while writing t he data to the NV
memory and stops receiving data. Therefore, be sure not to t ransmit data, including
the real-time commands, while t he pr i nter is BUSY.
• When <Function 48, 51, or 64> is transmitted, the data fol l owing 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 pL pH m fn
Hex 1D 28 4C pL pH m fn
Decimal 29 40 76 pL pH m fn
[Range] (pL + pH × 256) = 2 (pL = 2 , pH = 0)
m = 48
fn = 0, 48
[Description] • Transm i ts the entire capacity of the NV graphics area ( num ber 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 pL pH m fn
Hex 1D 28 4C pL pH m fn
Decimal 29 40 76 pL pH m fn
[Range] (pL + pH × 256) = 2 (pL = 2 , pH = 0)
m = 48
fn = 2, 50
[Description] • Pri nt s the buffered graphics data stored by the process of GS ( L <Functi on 112>.
