/. While you are experimenting
with Intermec Direct Protocol,
we recommend that you retain
the default verbosity setting (ON).
Later you should change it to
OFF, since this will produce
optimum printer performance.
Intermec EasyCoder 301 Direct Protocol 2.0 – Programmer's Guide Ed. 3
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 fields
in a predefined layout.
You can create counters without extensive programming.
You can easily enable the Feed key to produce printouts.
By default, verbosity is turned 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 immediately.
This method is used for setting up the printer, for returning
information from the printer back to the host and for managing
files, 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 fields
and such printable data that you do not need to change. Secondly,
send a string of printable data to the empty fields 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.
