A status enquiry command can only return one status code at a time. If there are two or more

simultaneous conditions, each condition should be cleared and the status enquiry repeated in

order to get a complete report of all status codes.

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.

NAK 11h Paused (ex. To avoid overheating of stepper motors)

NAK FFh Undefined error

Note • Errors 02h, 05h, and FFh are terminal faults that require you to reset the printer before

it will be operable again. A reset means that any data in the buffer is lost.

The printer automatically recovers from the other conditions as soon as the condition is

corrected, without data loss.

Note • If you want to read out all status information directly, use ESC ENQ E.

ESC ENQ 002

Paper-near-End Enquiry

1B 05 02 hex

27 5 2 decimal

Value = (01h) indicates “No paper”

Value = (00h) 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 00. 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.
