Paper Sensor Commands
Function Select Paper Sensor(s) to Stop Printing
ASCII [ESC] c 4 <n>
Hexadecimal 1BH 63H 34H <n>
Decimal <27> <99> <52> <n>
Range 0 n 255
Description ESC c 4 n selects whether to stop printing or not when the paper low is detected. There are three
sensors in the TM-U325D that are simulated in the POSjet 1500: the paper roll low, paper roll
end sensor, and validation sensor. The paper roll low sensor is enabled when either bit 0 or bit 1 is
on. The paper roll end sensor is enabled when either bit 2 or bit 3 is on. The validation sensor is
enabled when either bit 6 or bit 7 is on. When a paper low or a paper out is detected, printing stops
after printing the current line. The printer goes off line after printing stops. Installing a new roll
starts printing again. The default setting is n=12. If the paper roll low sensor or paper roll end
sensor is disabled and a paper out is detected, printing does not stop. The printer does not go off
line, and the Paper Out LED comes on. When the validation sensor is enabled and a paper-end is
detected, the printer ejects the paper after printing as much as possible and enters the paper
waiting state. When the validation sensor is disabled and a paper-end is detected, the printer does
not stop printing and eject the paper. It is possible to select multiple sensors to stop printing. Then
when any sensor detects a paper-end, printing stops. When a paper sensor is enabled with this
command, printing stops only when the corresponding paper is selected for printing. Print sheet
can be selected by using ESC c 0.
Note: The POSjet

does not allow the paper out sensor to be disabled.
The paper sensor(s) used to stop printing are selected by using n as follows:
