Who Should Read This Guide

This guide is helpful to every user, from the novice to the system manager.

How to Read This Guide

This guide is divided into two sections:

• Part 1 — Basic Operations
This section helps you set up your DEClaser 1152 on your PC, Apple

Macintosh, ULTRIX, or VMS system, and start printing right away. This
section assumes that the printer is set to the factory default settings. The
best way to use this section is to read the chapters that apply to your
operating system. It is not necessary to read the entire book sequentially.

• Part 2 — Advanced Operations
This section explains how to take advantage of the features of the

PostScript Level 2 DEClaser 1152 printer. This section covers these
topics:

Preface

• Using multiple communications channels

• Accessing and using fonts

• Using DECimage for picture enhancement
This guide does not cover all the features of the DEClaser 1152 printer

or your operating system. For more information about your printer,
see the DEClaser 1152 Printer Installation/Operator’s Guide. For more
information about your operating system commands and features, refer to
your host documentation.

PostScript Level 2 Features

The DEClaser 1152 is an Adobe PostScript Level 2 printer. A Level 2
PostScript printer includes all of the Level 1 operators with the additional
Level 2 operators. Although most Level 1 drivers will properly control the
DEClaser 1152, you will require a Level 2 driver to take advantage of the
benefits of PostScript Level 2. PostScript Level 2 drivers are available from
your vendors.

Some of the benefits of PostScript Level 2 are:

• Better performance for some compute-intensive jobs

• Better memory management for processing complex jobs

• Multiple-host capabilities

• Better control of some graphics capabilities

• Built-in file compression/decompression utilities

• Backward compatibility with Level 1 applications

This guide does not attempt to describe the language in detail, but will show
you how to set-up and use some of your DEClaser 1152’s Level 2 features.
For a complete description of the PostScript Level 2 language, refer to the
PostScript Language Reference Manual, Second Edition.

Software Requirements

When you print to the DEClaser 1152 printer, you may use any commands
your operating system supports. To use the commands listed in the following
chapters, this guide assumes that your operating system has the following
software installed:

Operating System Required Software

MS–DOS MS–DOS, Version 4.01 or higher
Microsoft Windows Microsoft Windows, Version 3.0 or higher
Apple Macintosh Apple Macintosh, System 6, System 7
ULTRIX ULTRIX, Version 4.0
VMS DECprint Supervisor for OpenVMS, Version 1.0

PostScript and PCL4 Files

The DEClaser 1152 printer primarily a PostScript printer. For applications
that do not have a PostScript printer driver, the DEClaser 1152 printer
provides Hewlett-Packard PCL4 emulation as an alternate language interface.
These two language interfaces are quite different in nature. This section
describes the differences between the two languages.

PostScript is a programming language designed to efficiently create what is
known as a ‘‘Page Description.’’ PostScript is a Page Description Language
(PDL). While PostScript is composed of only the printable ASCII characters,
it is not necessarily these characters that get printed on your printer. When
the DEClaser 1152 printer receives a PostScript file, the built-in PostScript
interpreter parses the file for instructions on how to create and lay out the
images and text to be placed on the paper.

The emulation of Hewlett_Packard’s PCL4 language is created from within
the PostScript interpreter. PCL4 is a Printer Control Language composed of
ASCII text embedded with special sequences of printer control instructions
that are preceded with the ASCII decimal 27 character, more commonly known
as the Escape character. The collection of printer control instructions is known
as escape sequences. With very few exceptions, the PCL4 emulator produces
output equivalent to the Hewlett-Packard LaserJet IIP printer.

When configuring the printer drivers in the following sections, keep in mind
that the DEClaser 1152’s communication channels are ready to interpret the
incoming data as a PostScript Language program.

Part1:

Basic Operations

The following chapters describe how to send a print job to the DEClaser
1152 printer from different platforms using the factory default settings of
the printer. The following DEClaser 1152 factory default settings satisfy the
requirements for most single-host configurations:

• Three enabled communications channels:

1. Parallel (Centronics)

2. Serial (Either EIA-232 or DEC423, not both)

3. LocalTalk

• All communications channels interpret the incoming data as PostScript.

• The serial communications settings are:

9600 Baud
8 Data Bits
1 Stop Bit
No Parity
XON/XOFF flow control

To change the default settings of the printer, see the DEClaser 1152 Printer
Installation/Operator’s Guide, which lists other settings that may also be
selected. See Chapter 4 to use this printer in a multihost configuration.

Installing and Using the DEClaser 1152

Printer with a PC

This chapter explains how to set up the DEClaser 1152 printer to print from
your PC running MS-Windows, Version 3.1 or MS–DOS, Version 5.0.

1.1 Connecting the DEClaser 1152 Printer to the PC

The DEClaser 1152 printer supports the following cables for PCs:

Cable Order Number

Parallel BC19M–10
DEC423 Serial BC16E–10 cable (included)
EIA-232 Serial H8571–E or H8571–J adaptor (See the DECdirect catalog for more

information.)

Most installations use the parallel cable for faster data transfer. We
recommend using the BC19M-10 or an equivalent parallel printer cable
(not included) to connect your printer to the PC.
