Programming Applications for the printer
The printer includes Honeywell Fingerprint, a programming language that
resides on the printer. Fingerprint is an easy-to-use programming tool for label
formatting and printer customization.
Fingerprint also includes a slave protocol, Honeywell Direct Protocol, which
allows layouts and variable data to be downloaded from a host and combined
into labels, tickets, and tags with a minimum of programming. Honeywell Direct
Protocol also includes a versatile error handler and a flexible counter function.
Fingerprint Commands for the printer
The ON PORTIN, PORTIN, PORTOUT, and ON PORTOUT Fingerprint commands
support applicator functionality for the printer. These commands are functional
when the printer applicator port status is enabled.
This section includes basic information for each of these commands. For more
information, see the Fingerprint Command reference manual.
ON PORTIN
This command allows a Fingerprint application to detect in signals. If a particu-
lar in signal is asserted, the application moves to the subroutine responsible for
carrying out tasks related to that in signal. One command is available for detec-
tion of each of the 8 in signals.
Note: This command is not supported by Honeywell Direct Protocol.

Description
External output signal.
Behavior depends on the current setup. Signal may be
asserted when there are no active events in the System
Health Monitor (SHM), when the printer motor is idle, or
both.
This signal is inactive when the Error Port option is
disabled.
Asserted low when an event in the System Health
Monitor (SHM) is activated. De-asserted when no events
are active in the SHM.
A "service required" event is also activated when the
Error Port is enabled and any applicator errors is
detected. This signal is also asserted when the Error on
Pause option is enabled.
