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 470 printer is capable of returning responses to enquiries in three different ways
depending on how the machine is programmed. (see software dip switch #1 position 1 and 2,
^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:
