You may be able to use the SYS$COMMON:[SYSHLP.EXAMPLES.DCPS]FONT_DOWNLOADER.COM command procedure to list, download, and delete fonts on the optional hard drive on a printer. The procedure is known to work with the DEClaser 5100 and LN17ps printers, and may work with other printers as well.
To use the procedure, invoke it and follow the prompts that it gives you.
This appendix explains the differences between the DECprint Supervisor
software and the DECprint Printing Services software, and their ability
to coexist. "DCPS" refers to the DECprint Supervisor for OpenVMS product;
"CPS" refers to the DECprint Printing Services product.
D.1 DCPS/CPS Coexistence
DCPS software can coexist on the same system with CPS Version 4.0 or
Version 4.1 software. The installation of DCPS software does not delete
or modify components of CPS software. You may continue to run both
products on the same system, or you may migrate the existing queue
structure from the CPS product to the DCPS product.
D.2 Printer Support
DCPS software provides support for new DIGITAL printers. When the
DCPS--Open license is loaded, the software also supports selected
third-party printers. See the DECprint Supervisor for OpenVMS SPD for more information.
D.3 DCPS$ 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/SYSTEM/EXECUTIVE 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.
The following are the values for DIGITAL printers:
DEClaser 3250: 0 manual feed/multimedia feeder 1* upper input tray 2 lower input tray 3 high capacity feeder (A/A4 only) DEClaser 2150 or 2250: 0 manual feed 1* lower input tray 2 upper input tray (duplex only) 3 power envelope feeder (if installed) DEClaser 1150 or 1152: 0* multipurpose (manual feed) 1 optional input cassette (if installed, becomes the default) PrintServer 20, 32, or 40: 1 upper 2 lower 3* LCIT PrintServer 17: 1 upper 2 lower * factory default |
This feature requires the DCPS--Plus license.
D.11 Stopping Unreachable PrintServer
If the operator issues STOP/QUEUE/RESET, and the queue is connected to
a DIGITAL PrintServer printer that is unreachable, the queue stops
properly. This was not always the case with the CPS V4.1 software.
D.12 Overwriting First Line
In the CPS V4.1 product, the top line was overwritten if the record
started with a form feed. This works correctly in the DCPS software.
D.13 Stall Timeouts
The CPS V4.1 software did not start the stall timer for directly-connected serial printers. The DCPS software starts the timer.
In the CPS V4.1 product, the default timeout for a stall message was
one minute. This frequently resulted in "queue stalled"
messages when the printer was processing a compute-intensive page (and
was not really stalled at all). In the DCPS product, the stall timeout
is four minutes.
D.14 Requeuing a Job
When a network error occurred while connecting to a printer, the CPS
V4.1 software would requeue the job with the /HOLD attribute. The DCPS
software requeues it without the /HOLD attribute.
D.15 Reading Stream Files
If a PostScript file has a record attribute of STREAM, STREAM_LF, or
STREAM_CR, it is read in head1 mode. This allows the DCPS software to
print very long stream records that the CPS software cannot print.
Files of this type are sometimes written by PC communications programs.
D.16 Copies Start on New Sheets
When /COPIES=n is requested, and n is more than one, each copy
starts on a new sheet, even when printing with NUMBER_UP or SIDES=2.
This was not the case with PostScript jobs in the CPS V4.1 product.
D.17 Generic Queues Restarted
On shutdown, OpenVMS stops execution queues but not generic queues. As
a result, when the system starts up again, the generic queues begin
running even though they may have the wrong characteristics. When you
start up generic queues in the CPS V4.1 product, you get warning
messages saying that the queues are already running (as of OpenVMS
V5.5). When the DCPS software starts up generic queues, it stops and
then restarts those that are already running.
D.18 Proprinter Translator
The DCPS software contains a new Proprinter-to-PostScript translator
not available in the CPS product. For general information on using the
PROPRINTER data type, see the User's GuideUser's Guide.
D.19 DCPS and PATHWORKS Libraries
PATHWORKS for OpenVMS (Macintosh) creates its own device control
library, MSAP$DEVCTL.TLB, and also puts its modules into the CPS
library if there is one. It does not put them in the DCPS library. To
rectify this, define DCPS_LIB as a search list that points to both the
DCPS and PATHWORKS libraries. An example in DCPS$STARTUP.TEMPLATE shows
how to do this.
D.20 Printing with Macintosh & PC Files
The DCPS software contains a new PostScript example file to improve
printing of Macintosh and PC files on DIGITAL's PrintServer printers.
D.21 Improved Color Function for Colormate PS
The color transfer function of the Colormate PS has been changed to avoid the problems of gray scale images that are muddy or brown, and natural images with poor flesh tones. The Colormate PS now runs prints with a new default color transfer function to provide better gray scale images and natural flesh tones. Consequently, you may notice the following changes when you print on the Colormate PS:
The DCPS product provides a new example file:
SYS$COMMON:[SYSHLP.EXAMPLES.DCPS]CONFIDENTIAL.PS |
This file shows how to redefine the showpage operator to write "Confidential" at the top and bottom of each page as an overlay (that is, after the contents of the page have been imaged).
