Principles of Operation

1. Intermec Direct Protocol Special Features

1
/. While you are experiment-
ing with Intermec Direct
Protocol, we recommend that
you retain the default ver-
bosity setting (ON). Later
you should change it to OFF,
since this will produce opti-
mum printer performance.

2. Sending Commands

8
There is a built-in error handler, that can indicate selected error
conditions and produce error-messages of your own creation in
any language you like.
Variable input data (in a special format) can be inserted into fi elds
in a predefi ned layout.
You can create counters without extensive programming.
You can easily enable the Feed key to produce printouts.
By default, verbosity is On in Intermec Direct Protocol
Intermec Direct Protocol allows you to send commands to the
printer in two ways:
• Immediate Mode
• Layout Mode
• Immediate Mode
You send commands that the printer will act upon immedi-
ately. This method is used for setting up the printer, for
returning information from the printer back to the host and
for managing fi les, fonts and images.
Examples:
PRINT KEY ON ↵
? DATE$ ↵
KILL "LAYOUT1" ↵
Immediate Mode can also be used for creating label layouts
including all the printable data as illustrated below.
• Layout Mode
Layout Mode is only intended for creating labels. Firstly, create
a layout containing formatting commands for a number of
fi elds and such printable data that you do not need to change.
Secondly, send a string of printable data to the empty fi elds
plus a print command. You can create a number of different
layouts, select the one you need, add the variable data, and
print out the labels.
