Preface

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:

• 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.

Conventions

The following terms and conventions are used in this guide.

Term/Convention Meaning

Note Provides additional information.

Caution Provides information for preventing equipment or

software damage.

Warning Provides information for preventing personal injury.

Bullet (



) A bulleted statement in a procedure describes a result

after performing a step.

Bold type Text in boldface designates messages that appear on the

control panel and menu options in DECwindows.

Term/Convention Meaning

filename

Represents a generic ﬁle name. Replace it with the name

and extension of your ﬁle, using your operating system’s

syntax.

queuename

Represents a generic queue name. In commands, replace

it with the name of a real queue.

ENTER Represents the key to press on the control panel.

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.
