[ESC] p 4 Select paper sensor(s) to stop printing
ASCII [ESC] p 4 <n>
Hexadecimal 1BH 70H 34H <n>
Decimal <27> <112> <52> <n>
Range 0 ≤ n ≤ 255
Description The [ESC] p 4 <n> command selects which sensors tell the printer to stop
printing. For the default setting, 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 Epic 880

printer does not allow the Paper Out sensor to be
disabled. It is always on.
<n> is defined as follows:
Bit On/Off Hexadecimal Decimal Function
0,1 Off 00H <0> Paper roll near-end sensor disabled
On 01H,02H,03H <1>,<2>,<3> Paper roll near-end sensor enabled
7 - 00H <0> Undefined

[ESC] p 3 Select paper sensor(s) to output paper-end signals
ASCII [ESC] p 3 <n>
Hexadecimal 1BH 70H 33H <n>
Decimal <27> <112> <51> <n>
Range 0 ≤ n ≤ 255
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.
