Set burn time
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.
Example:
!Z 20 <CR><LF>
sets burn time 640 µs
The burn time setting is stored in the
non-volatile memory.
Power off/on reset returns the setting
to default value.
CAUTION! –
A longer burn time put 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.

immediately after receipt, whereas the !S command is effected in sequence when
received.
