This appendix provides some information about OpenVMS logical names that are used by the DECprint Supervisor for OpenVMS software.
Here are some guidelines for using these logical names:
Below is a table of the logical names used by DCPS, their acceptable values, and a brief explanation of what they mean. There are also references to other sections of this document or other documents where you can find more information about the logical names.
In the following table, qn is an abbreviation for the queue name. |

You may be able to use the SYS$COMMON:[SYSHLP.EXAMPLES.DCPS]FONT_DOWNLOADER.COM command procedure to list, download, and delete fonts on the optional hard drive on a printer. The procedure is known to work with the DEClaser 5100 and LN17ps printers, and may work with other printers as well.
To use the procedure, invoke it and follow the prompts that it gives you.
This appendix explains the differences between the DECprint Supervisor
software and the DECprint Printing Services software, and their ability
to coexist. "DCPS" refers to the DECprint Supervisor for OpenVMS product;
"CPS" refers to the DECprint Printing Services product.
D.1 DCPS/CPS Coexistence
DCPS software can coexist on the same system with CPS Version 4.0 or
Version 4.1 software. The installation of DCPS software does not delete
or modify components of CPS software. You may continue to run both
products on the same system, or you may migrate the existing queue
structure from the CPS product to the DCPS product.
D.2 Printer Support
DCPS software provides support for new Compaq and DIGITAL printers.
When the DCPS--Open license is loaded, the software also supports
selected third-party printers. See the DECprint Supervisor for OpenVMS SPD for more
information.
D.3 DCPS$ Prefix
All file names, logical names, and messages for the DCPS product start with the DCPS$ prefix. This ensures that you can continue to use CPS software to drive some queues, and add the DCPS software to drive others. The default OpenVMS form is DCPS$DEFAULT.
Certain files, however, are considered system resources, and are shared between the DCPS and CPS products, and possibly other products. These shared resources are:
Secondary messages (those generated by other facilities such as RMS,
and passed along by the DCPS product) retain the code of the facility
that originated the message.
D.4 Startup File Converter
The conversion tool, CPS_TO_DCPS_STARTUP.COM, converts the startup file for the CPS software so that it uses the names from the DCPS product. This tool is described in Section 3.2.
The following table lists the CPS_Name and the corresponding DCPS_Name conversions.
| CPS_Name | DCPS_Name |
|---|---|
| CPS$STARTUP | DCPS$STARTUP |
| CPS$EXECUTION_QUEUE | DCPS$EXECUTION_QUEUE |
| CPS$REQUIRED | DCPS$REQUIRED |
| CPS$GENERIC | DCPS$GENERIC |
| CPS_LIB | DCPS_LIB |
| CPS$DEVCTL | DCPS$DEVCTL |
| LPS$ queuename_PARAMETER | DCPS$ queuename_PARAMETER |
| CPS$ queuename_STALL_TIME | DCPS$ queuename_STALL_TIME |
| LPS$LAYUP | DCPS$LAYUP |
| DECprint Printing Services | DECprint Supervisor |
The conversion tool does not change queue names or the structure of the queues.
D.5 Eliminating Generic Queues
DCPS software, when used with the DCPS--Plus license, has the ability
to automatically detect data types, so you may be able to reduce the
number of generic queues or eliminate them altogether. Refer to the
System Manager's GuideSystem Manager's Guide for more information on automatic data type detection.
D.6 Page Scaling
The DCPS product can scale the logical page image to fit the output sheet if the system has the DCPS--Plus license loaded, and if the job provides the following parameters:
PAGE_SIZE=p,SHEET_SIZE=s |
Note that p and s are different values.
The job assumes the parameter NUMBER_UP=1. With CPS, it was necessary
to explicitly provide a NUMBER_UP parameter in order to trigger page
scaling.
D.7 Layup for PS Level 2 Printers & Layup Fixes
The DCPS software layup facility supports PostScript Level 2 operators when connected to printers that implement PostScript Level 2. It also fixes or extends support for several Level 1 operators.
Level 1 PostScript programs produced by Macintosh and PC applications
generally print better with the DCPS product than they did with the CPS
product. Problems with CorelDraw and Macintosh programs have been fixed.
D.8 Layup Options on PRINT Command Line
With DCPS software, you can provide layup options directly with the LAYUP_DEFINITIONS parameter, or you can record those options in a .LUP file and provide that file name with the parameter. Providing the layup options on the PRINT command makes it possible to pass them with jobs to be printed on another system via the Distributed Queuing Services product. CPS V4.1 software offers only the .LUP file option.
See the User's GuideUser's Guide for information on expressing layup options in a layup definition file or as a PRINT parameter.
D.9 Page Sizes
In the CPS V4.1 product, the following page sizes did not exist or were
not correctly interpreted. The DCPS product defines and interprets
these correctly.
To select job separator pages from an alternate tray using the DCPS software, define the following system logical:
$ DEFINE /EXECUTIVE_MODE /SYSTEM DCPS$queuename_SEPARATOR_TRAY number |
Note that number is a valid tray number for the printer served by that queue, and is printer-specific. Refer to your printer documentation to obtain the correct value.
This feature requires the DCPS-PLUS license.
