Preface

Intended Audience

This manual is for OpenVMS system managers and data center operators. Using this guide, you can create and modify print queues, maintain the print jobs and print queues, and set up printing environments to meet the needs of the printing system users.

This guide is also intended for advanced users and applications programmers who customize the printing system using form definitions, setup modules and layup definition files. The User's GuideUser's Guide describes how users access the features of the printing system.

Be sure to read the Software Installation GuideSoftware Installation Guide if you have not installed the DECprint Supervisor software.

Conventions

The following conventions are used in this manual:
Ctrl/ x A sequence such as Ctrl/ x indicates that you must hold down the key labeled Ctrl while you press another key or a pointing device button.
[Return] In examples, a key name enclosed in a box indicates that you press a key on the keyboard. (In text, a key name is not enclosed in a box.)

In the HTML version of this document, this convention appears as brackets, rather than a box.

... A horizontal ellipsis in examples indicates one of the following possibilities:
  • Additional optional arguments in a statement have been omitted.
  • The preceding item or items can be repeated one or more times.
  • Additional parameters, values, or other information can be entered.
( ) In command format descriptions, parentheses indicate that you must enclose choices in parentheses if you specify more than one.
[ ] In command format descriptions, brackets indicate optional choices. You can choose one or more items or no items. Do not type the brackets on the command line. However, you must include the brackets in the syntax for OpenVMS directory specifications and for a substring specification in an assignment statement.
| In command format descriptions, vertical bars separate choices within brackets or braces. Within brackets, the choices are optional; within braces, at least one choice is required. Do not type the vertical bars on the command line.
{ } In command format descriptions, braces indicate required choices; you must choose at least one of the items listed. Do not type the braces on the command line.
bold text This typeface represents the introduction of a new term. It also represents the name of an argument, an attribute or a reason.
italic text Italic text indicates important information, complete titles of manuals or variables. Variables include information that varies in system output (Internal error number), in command lines (/PRODUCER= name) and in command parameters in text (where dd represents the predefined code for the device type).
UPPERCASE TEXT Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.
Monospace text Monospace type indicates code examples and interactive screen displays.
- A hyphen at the end of a command format description, command line or code line indicates that the command or statement continues on the following line.
numbers All numbers in text are assumed to be decimal unless otherwise noted. Nondecimal radixes---binary, octal or hexadecimal---are explicitly indicated.

DCPS Overview

1.1 Purpose of the DCPS Software

The DECprint Supervisor software allows people to use and manage networked PostScript printers. For example, it allows users to:

The system manager makes the printing system easier to use by providing:

DCPS also provides the following features:

DCPS Version

The version of DCPS software currently running on your system is printed on job and file separator pages, as well as in the logical name DCPS$VERSION. If DCPS$VERSION is undefined, DCPS has not been started on the system.

1.2 DCPS Software Components

The DECprint Supervisor software includes the following components:

The DECprint Supervisor symbiont is used in place of the OpenVMS print symbiont, PRTSMB. The software is distributed as executable image files, text, and help files.

Figure 1-1 illustrates the process by which print jobs are produced on an OpenVMS system and delivered to the printer.

Figure 1-1 DCPS Software Components


The software components of a DECprint Supervisor printing system are described in the following sections.

1.2.1 The Print Symbiont

Users send jobs to the printer using the DCL PRINT command or using an application program that generates the OpenVMS system service call SYS$SNDJBC. The print symbiont manages the print jobs. The DECprint Supervisor software performs the following operations:

For example, suppose a user issues the following PRINT command:


    $ PRINT /QUEUE=POST3 /NOTIFY THORNTON.TXT

The PRINT command line is translated to system service calls, which are sent to the job controller. The calls are converted to job controller data structures, which are then passed to the symbiont for processing. The symbiont sends the processed arguments and file data to the printer and notifies the user by displaying messages about the status of the print job.

See the User's GuideUser's Guide for information about the PRINT command and its qualifiers.

1.2.2 Device Control Libraries

A device control library is an OpenVMS text library that contains setup modules. The symbiont uses modules from the device control library to implement the various PRINT parameters. The DECprint Supervisor software extracts the appropriate module, depending on the qualifier that either appears on the PRINT command line or is associated with a print queue, and inserts the module into the data stream.

The device control library also contains modules that the symbiont does not automatically use. Some of these modules contain PostScript procedures, for example, to include an error handler in a print job or to extend the findfont procedure to recognize alternate character encodings. These are described in the User's GuideUser's Guide.

You can create setup modules to be used on your own systems. When you create setup modules, you must store them in a device control library other than the DCPS$DEVCTL library. Create a device control library as described in Chapter 7 and add your library to the device control library search list defined in DCPS$STARTUP.COM.

When you create a site-specific device control library for your custom setup modules, the contents of your library are retained from one version of the DECprint Supervisor software to the next. The standard device control library, DCPS$DEVCTL, is overwritten when you upgrade from one version of the software to the next.

1.2.3 Translators

When a print job submits a print file that is not PostScript (or PCL, if your printer has a native PCL interpreter), the symbiont invokes a translator to translate the user's input file into PostScript. (Refer to Chapter 4 for more information about customizing the printing system for certain types of files.)

DECprint Supervisor software can detect the file data type automatically. You need not specify the data type on the PRINT command line. Translation to PostScript for successful printing is automatic. It is not necessary to maintain generic print queues for default data types.

The system manager can associate a default data type with a generic print queue, allowing users to print files by specifying the generic queue name. See Chapter 3 for more information.

If DCPS incorrectly identifies the data type of a file, you can identify the data type on the command line:


    $ PRINT MYFILE.MEM /PARAMETERS=DATA_TYPE=ANSI
    $ PRINT MYFILE.POST /PARAMETERS=DATA_TYPE=POSTSCRIPT
