[Function]
<Thermal>
Sets to make 180˚ inversion function valid/invalid.
k 180˚ Inversion Function
0 Invalid
1 Valid
<180˚ Inversion Function>
When the 180˚ inversion function is valid, it is executed by the 180˚ inversion trigger.
However, this function is executed on print data that fits in the image buffer length.
If print data is larger than the image buffer length, the 180˚ inversion function is ignored.
Also, when starting printing using anything other than the 180˚ inversion trigger, the 180˚ inversion
function is ignored.
This setting is not cleared by the ESC @, CAN commands.
180˚ Inversion Triggers
• Cutter Command: ESC d n
• FF Command: FF
• BM Detection Command: ESC d n, FF
• Print Startup Command: ESC GS g 0 m n
• Raster Mode: When executing FF
Example of Use
*1) 180˚ Inversion Function Valid: ESC GS h 0 k m n (k=0x01, m=0x00, n=0x00)
2) Transmit print data: Print data (print length is within the length of the image buffer)
3) Trigger command transmission: ESC d n (cutter command is 180˚ inversion trigger)
<Slip>, <Validation>
Only setting is valid
Setting is valid after switching to thermal.
(Note) When using this function, the data volume for one page should be within the printer’s
buffer length.
