5.2 PRINTER ENQUIRIES

It is important for the host computer to know the status of the printer as labels are produced. This

facilitates security in the system and flags electrical and mechanical errors. Enquiries can also be

used to adjust the pace of the printer with that of the operator.

The 465 printer is capable of returning responses to enquiries in three different ways depending on

how the machine is programmed. (see software dip switch1 #1, ^D21, Section 5.3.) The text

equivalent response returns a text string, giving the state of the machine. The ^ equivalent returns

an ASCII '^' response followed by the defining alpha character. The control code equivalent returns

an actual control code.

The printer will send to the host one of the following responses in response to a ^E or ^D55:
