Control Codes
4.1.1

Standard Emulation

The standard control codes for the Series 90PLUS Printer are extensions and subsets of the IBM emulation
provided on other PcOS products. In some cases, an application designed for a Series 50 Printer with IBM
code sets will function with a Series 90PLUS Printer. There are, however, significant differences in the
operation of the Series 90PLUS Printer that may impact existing applications.
4.1.2

EPOS Emulation

5
ESC/POS is referred to here as EPOS. The Series 90PLUS Printer supports an EPOS emulation with
extensions. The emulation is designed to allow the Series 90PLUS Printer to be used with Seiko Epson
printer applications. It is intended that the standard emulation be used for new applications. Not all features
of the Series 90PLUS Printer are supported by EPOS.
This guide will include the EPOS code equivalent for features of the Series 90PLUS Printer that are
supported by EPOS. When EPOS commands are significantly different from the standard emulation, an
independent EPOS description is provided.
4.1.3

IPCL Codes

Ithaca Printer Control Language (IPCL) codes are designed to control a printer without using control
characters, i.e., characters less than 20H. Only the standard emulation supports IPCL. Not all commands are
supported by IPCL codes. For the commands that are supported, the IPCL code is listed.
In rare cases, an IPCL code will interfere with the text that is to be printed. The IPCL translator can be
disabled with an [ESC] y <4> command.

4.2 Application Development

To aid in application development, there are several sections in this guide that are designed to help the
programmer understand the Series 90PLUS Printer. The first is a detailed description of each of the commands.
The second section is an explanation of how the printer works. It explains the internal print buffer, the
communication link, and how the host computer and printer interact. The third is a description on how to use the
CFG90 program to help develop applications.

4.3 Tables and Charts

Throughout this guide, there are charts and tables that list commands and features. In most cases, these charts
cross-reference the page that describes the command. Commands are grouped by function and can at times be
hard to find. To minimize the time it takes to find commands, there are two code summary charts in the
following section, one ordered by code and one by function.
