Introduction - Intermec ESim v4.20 Programmer's Reference Manual

Preface

Introduction

Th e EasyCoder C4 printers from Intermec are provided with a built-in
protocol (ESim) by which you can use any computer, terminal, scanner
or keyboard, that can produce ASCII characters, to control the printer.
Th is is a useful alternative to the Intermec InterDriver, which requires a
PC operating under Microsoft Windows.
With the ESim protocol, you can use any editor to control the printer,
either by means of the serial RS-232 channel or the parallel Centronics
channel.
Th e EasyCoder C4 ESim protocol is compatible with the corresponding
protocol for EasyCoder 91, even if some commands or command param-
eters have no meaning in EasyCoder C4, and some commands are new.
Note that EasyCoder C4 has a fl ash memory for forms and graphics,
which requires special consideration. Avoid storing frequently changing
data in fl ash (see GM and GW commands in Chapter 7) and use printer
drivers developed for EasyCoder C4 rather than EasyCoder 91 drivers.
Th is manual will assist you in designing labels using the ESim protocol. It
has been organized to provide you with an under-standing of the printer's
functions and command structure.
Th e manual describes version 4.20 of the ESim protocol.
If you have any questions regarding the protocol or this manual, please
contact your Intermec distributor for technical assistance.
