The host computer cannot be certain that all conditions have been cleared until an ACK is
received.
The possible conditions are reported in the above order.
This command requests a paper-near-end sensor (paper low) status from the printer in a 1-byte
format.
Note • If you want to read out all status information directly, use <ESC><ENQ>E.
ESC ENQ 2
Paper-near-end Enquiry
1B 05 02 hex
27 5 2 decimal
Value = 1 indicates ”No paper”
Value = 0 indicates ”Paper present” at the sensor position
Note • The status of the sensor is sampled every time the printout is cut. If three succeeding
samples show "no paper", the status reply changes to 1. This is to prevent false alarm if the
side of the paper roll is not clean. If you want the momentary status of the sensor, use
<ESC><ENQ><6>
and extract the paper-near-end bit.
