Description The [ESC] p 4 <n> command selects the sensors that tell the printer to
stop printing. The default setting occurs when only the Paper Out sensor
stops printing. When the paper roll near-end sensor is enabled and the
sensor detects a near-end condition during printing, the printer completes
the current line and then automatically goes off-line. Replacing a new
paper roll restarts the printing. When the paper roll near-end sensor is
disabled and a paper near-end condition is detected during printing, the
paper out LED comes on, but the printer continues to print.
Note: The ITherm

does not allow the Paper Out sensor to be disabled. It
is always on.
<n> is defined as follows:

0,1 Off 00H <0> Paper roll near-end sensor disabled
On 01H,02H,03H <1>,<2>,<3> Paper roll near-end sensor enabled

Description The [ESC] p 3 <n> command selects the paper sensor that outputs a
paper-end signal to the parallel interface when a paper-end is detected.
The default setting is when all sensors are enabled. (<n> = 15). It is
possible to select multiple sensors to output signals. If any of the sensors
detect a paper end, the paper end signal is output. The command is only
available with a parallel interface. The paper-end sensor is an option. If
the sensor is not equipped, the settings of bits 0 and 1 of the command
are not effective.
