P1003642-001 TTPM3 Installation and Programming Manual 01/06/2009
The burn time controls the print density. It is used to set the heating so that it is adequate for
the thermal paper used as ticket material. Set it to the lowest burn time that gives acceptable
print quality.
The burn time setting is stored in the non-volatile memory.
Power off/on reset returns the setting to default value.
The TTPM3 responds by sending the same 1 byte response to the host computer as is sent as
byte 1 in response to the !S command. The ENQ command is effected immediately after
receipt, whereas the !S command is effected in sequence when received.

Caution • A longer burn time puts more load on the printhead, so do not use a longer burn
time than required for a clearly legible print. Settings over 27 are not recommended.
