# Chapter 1
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:

- Print customized documents, print two-sided, and select input trays.
- Modify printed documents without changing the files that are printed, which saves paper and allows the production of custom printed documents.
- Print different types of files on the PostScript printers.
- Access printers from the OpenVMS Alpha and VAX operating systems and from personal computers (PCs) and Macintosh systems.

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

- Default queue attributes, so users do not have to specify certain parameters, such as duplex printing
- Setup modules, which are stored in device control libraries and are used to modify the printing environment for print jobs
- Form definitions, specifying sets of print attributes and including setup modules to make them all easier for users to access
- Layup definition files, which you can create to customize the way print jobs are printed on the media

Note Starting with DCPS V2.0, the need for DCPS-OPEN and DCPS-PLUS licenses has been eliminated. The right to use all features of DCPS is now included with the OpenVMS operating system license.

DCPS also provides the following features:

- Document Formatting
  DCPS allows users to:
  - Change the size of pages as they are printed to fit the physical size of media, using the following command:

        $ PRINT/PARAMETERS=(PAGE_SIZE=n,SHEET_SIZE=m) file-spec

  - Specify page layup handling as the file is printed, using the following command:

        $ PRINT/PARAMETERS=(LAYUP=option=value)

  - Save paper, using one of the following commands:

        $ PRINT/PARAMETERS=(PAGE_LIMIT="n,m")
        $ PRINT/PARAMETERS=(NUMBER_UP=n)

  - Print multiple uncollated copies of each sheet via the SHEET_COUNT parameter.
  - Use device control modules for all data types via the /SETUP qualifier. ANSI modules may include control sequences. PCL modules may include binary font data.
- Data Type Translation
  DCPS lets users print additional file data types, including:
  - PCL 4 (Printer Control Language) files generated for printing on Hewlett-Packard LaserJet IID devices
  - Proprinter files generated for printing on IBM Proprinter XL24 devices
  - ReGIS graphics files (monochrome output only)
  - TEKTRONIX files, generated for printing on TEKTRONIX 4010/4014 devices
  - ASCII text files, to be printed with line numbers, page headers, and alternating groups of gray and white bars
  - DIGITAL Document Interchange Format (DDIF) bitonal image files
- Automatic Data Type Detection
  Users do not need to specify the data type of the print file, in most cases. DCPS recognizes files of the supported data types and automatically translates them to PostScript before printing.
  DCPS can print files that contain both text (ANSI, PCL, or Proprinter data) and PostScript data. For example, users can print electronic mail messages that contain PostScript files. The user submits the print job without specifying any data type. The DCPS software begins printing the file as text and automatically recognizes the change to PostScript, printing the file properly.
  See Chapter 4 for information about customizing the printing system to recognize and print the files generated by users at your site.

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:

- A print symbiont, which processes print requests from OpenVMS print queues assigned to the printer
- Queue management services, as described in Chapter 5
- Data type translators to translate non-PostScript files for printing on PostScript devices
- A device control library for setup modules that affect the printing of files, as described in Chapter 7

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:

- Maintains resources
- Sends control data to the printer
- Sends the data file to the printer
- Monitors printer progress
- Reports printer status
- Handles exceptions

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
