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.

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
	This command requests a paper-near-end sensor (paper low) status from the printer in a 1-byte
	format.
	Value = 1	indicates ”No paper”
	Value = 0	indicates ”Paper present” at the sensor position

57

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.
