Introduction
Intermec EasyCoder 301 Direct Protocol 2.0 – Programmer's Guide Ed. 3
Intermec Direct Protocol is an easy-to-use printer programming lan-
guage that has been developed for use with the computer-control-
led direct thermal and thermal transfer printers manufactured by
Intermec. The version described in this manual is only applicable to
EasyCoder 301 printers, but is in most respects compatible to other
versions of the Intermec Direct Protocol, so applications created
for other types of EasyCoder printers can be used on an EasyCoder
301 with few or no modifications.
Intermec Direct Protocol can be used in two ways:
• To create label layouts consisting of fields with fixed or variable
information. A layout can then be selected and provided with
variable input from the host computer in the form of a simple
string of data.
• To send input data and formatting commands as a continuous
string of data directly from the host computer.
In both cases, Intermec Direct Protocol provides a flexible error
handler, which allows you to compose your own error messages in
any language.
Intermec Direct Protocol has been created with two main types of
application in mind:
• Applications where the end-user requires a simple printer control
program, but needs a versatile error handler.
• Applications which have a comprehensive printer control program
in the host computer.
Refer to chapter 13 in this manual for lists of the various commands
in Intermec Direct Protocol.
We recommend that you have the following manuals accessible
when you perform any programming:
• EasyCoder 301 Installation and Operation Manual
• This Programmer's Guide.
