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 operating system 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
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.
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.
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.
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.
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
