Reading Sensors And Straps; Reading Printer's Status - Intermec EasyCoder 501XP Programmer's Reference Manual

Chapter 7 — Reading the Printer's Status

7.7 Reading Sensors and Straps

There are a number of sensors, hardware strap, and setup parameters in
the printer that can be read and their status or value be returned to the
host:
? SYSVAR (<parameter>)
<parameter> = 18
<parameter> = 19
<parameter> = 20
<parameter> = 23
<parameter> = 26

7.8 Reading Printer's Status

The printer's status in regard of various errors and other conditions can
be read and returned to the host using the
? (PRSTAT AND <parameter>)
<parameter> = 0
<parameter> = 1
<parameter> = 2
<parameter> = 4
<parameter> = 8
<parameter> = 16
<parameter> = 32
Parameters can be combined, for example <3> checks for both "printhead lifted" and "label not removed"
conditions. The printer will return 1 (= yes) or 0 (= no).
The version of the Intermec Direct Protocol, the type of printer family,
and the type of CPU board can be read using a
? VERSION$[(type of info)]
<type of info> = 0
<type of info> = 1
<type of info> = 2
