2.9 Printer Name Is Not Always Printed Correctly
When multinational characters are used in the PostScript ‘‘printername’’, the
printer name printed on the bottom of separation pages may be printed in the
wrong character set.
2.10 DDIF Printing Requires DECwindows Software or DECimage
Application Services
To print DDIF encoded bitonal images, DCPS requires that either DECwindows
software or Version 3.1 of DECimage Application Services (DAS) be installed on
your system. DAS is only available on OpenVMS VAX systems.
2.11 Compatibility of NUMBER_UP and PostScript Drivers
PostScript files created with the LaserWriter 8.0 or 8.1.1 driver or the Adobe 2.1.1
Windows driver in conjunction with the application may produce PostScript files
that do not print as expected with NUMBER_UP greater than 1.
Symptoms include pages being clipped, printed outside of the NUMBER_UP page
spots, or being improperly scaled.
2.12 LIST Translator Ignores PAGE_SIZE Parameter
The LIST translator ignores the PAGE_SIZE parameter when formatting pages.
It creates pages with maximum content at a size adequate for both A (Letter) and
A4 paper:
PORTRAIT ORIENTATION: 80 columns, 70 lines
LANDSCAPE ORIENTATION: 150 columns, 66 lines
It is still possible to use PAGE_SIZE and SHEET_SIZE parameters together
(with the DCPS-PLUS license) to scale the logical page onto a different size
sheet.
2.13 Embedded PJL Commands Discarded; Avoid Binary Mode
Drivers that create files for PJL printers, such as those for the DEClaser 5100
and the HP LaserJet IV family, include printer control commands in HP Printer
Job Language (PJL). DCPS filters out and discards that data. Therefore, printer
options selected by such drivers do not affect the print job.
When using these drivers, do NOT select binary mode. It will insert additional
commands into the file that can cause incorrect behavior when printing via
DCPS. The exact form of behavior depends on which printer is actually connected
to the queue and whether or not the job passes through a DCPS translator.
2.14 Unreliable Communication After Errors on Some Printers
Unexpected errors can occur at the end of a print job when printing to some
printers using the AppleTalk interconnect. The printers which can exhibit
problems include the LaserWriter Pro 600, LaserWriter Pro 630, the LaserWriter
IIg, and the LaserWriter IIf. Generally, the unexpected error occurs when an
explainable error occurred during the print job; for example, a PostScript error
which causes the PostScript interpreter to ‘‘Flush to the EOJ’’, or a timeout error
while waiting for manual feed. The behavior a user may see includes one of more
of the following:
• A second PostScript error or timeout error occurs
