Paper sensor status (
n
= 1, 49)
The paper roll near-end sensor is an option. If the printer is not equipped with the paper
near-end sensor, bits 0 and 1 of the third byte are always ON, “Paper adequate”.
When the paper roll end sensor detects a paper-end, the printer goes off-line and does not
execute this command. Therefore, bits 2 and 3 of the paper sensor status do not transmit a
paper-end status.
