Select maximum print speed
EIA-232 Syntax:
ESC ? nor X'1B;2F;n'
where:
n=00 52 lines per second
n=01 35 lines per second
n=02 26 lines per second
n=03 15 lines per second
Default:
n=00
Remarks:
vIn the cash receipt station, the printing will slow down to the maximum
selected speed. This will increase the quality of the printing and lower the
current draw from the power supply when printing high density images,
such as dark logos.
vThis is the maximum speed being selected, so the dot utilization
algorithms can still slow the speed further when necessary.
vIf MCT 11hex (17 dec), bit 11 has been set to a value of zero (maximum
speed of 35 lps), then this command will not have an effect on the
maximum print speed (the MCT value takes precedence).
vThis command does not affect the document station.
vThis command is not supported in TI-1/2 printers.
vThis command used to be called set/cancel high quality print mode
and only supported parameter byte values of 0 and 1. Code level 40
added parameter byte values of 2 and 3.
