Control Codes Overview

NCR2567 Emulation

The standard control codes for the Series 150 Printer are extensions and subsets of the NCR2567
emulation provided on other PcOS products. In all cases, an application designed for a Series 50
Printer with NCR2567 code sets will function with a Series 150 Printer. There are, however,
more features in the Series 150 Printer that can be used for new applications.

Telpar Emulation

The standard control codes for the Series 150 Printer are extensions and subsets of the Telpar
emulation provided on other PcOS products. In all cases, an application designed for a Series 50
Printer with Telpar code sets will function with a Series 150 Printer. There are, however, more
features in the Series 150 Printer that can be used for new applications.

Application Development

To aid in application development and help the programmer understand the Series 150 Printer, this
manual is broken down into two major sections. The first section 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 communications link, and how the host computer and printer interact.

Tables and Charts

Throughout this guide, there are charts and tables that list commands and features. In most cases, the
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.
