Introduction - Intermec EasyCoder PD4 Programmer's Reference Manual

Chapter 1—General Information

Introduction

The EasyCoder PD4 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.
This 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, the parallel Centronics
channel, or the USB channel.
Note that EasyCoder PD4 has a flash memory for forms and graphics,
which requires special consideration. Avoid storing frequently changing
data in flash (see GM and GW commands in Chapter 7) and use printer
drivers developed for EasyCoder C4 and PD4.
This manual will assist you in designing labels using the ESim protocol. It
has been organized to provide you with an understanding of the printer's
functions and command structure.
The manual describes version 5.12 of the ESim protocol.
If you have any questions regarding the protocol or this manual, please
contact your Intermec distributor for technical assistance.
