Technical data

• DCPS unexpectedly loses communication with the printer
• The job trailer page (if specified) may not print
• The page count in the accounting file is not correct
• A delay of up to one minute before the job completes.
The user’s part of the print job prints as expected. The unexpected error occurs
during the end of job processing (for example, getting the page count or the job
trailer page printed) done by the DECprint Supervisor. Once the offending job is
complete, subsequent jobs print as expected. No system operator intervention is
needed.
2.15 Deleting Job When Using AppleTalk
When printing using an AppleTalk interconnect, a request to delete a job
(DELETE/ENTRY) is accomplished by closing the connection to the printer. The
AppleTalk protocol does not provide for interrupting the PostScript interpreter;
therefore, the printer will continue to print page descriptions that are contained
in its buffer before it stops printing the job. A job trailer page will not be
printed.
2.16 Avoid STOP/QUEUE/RESET Usage for PrintServer Printer
Which Is Rejecting Connections
If you issue a STOP/QUEUE/RESET command for a queue to a DIGITAL
PrintServer printer while there is a job in the ‘‘Starting’’ state and while the
printer is rejecting connections (because, for example, the PrintServer is powered
off or is booting), the queue will stop. Occasionally the symbiont process will not
terminate. Avoid issuing this command until the PrintServer printer becomes
available. If the job is in the ‘‘Starting’’ state and also in the PrintServer printer’s
job queue, a STOP/QUEUE/RESET will execute correctly.
2.17 No Job Trailer Page on DELETE/ENTRY
If you issue a DELETE/ENTRY command when the printer is printing the job
trailer page, it is possible to delete the printing of this page. Also, if you issue a
DELETE/ENTRY command for a job printing on a PrintServer printer after all
the data for the file is sent, it is possible that the job trailer page will not print.
2.18 Problems with PostScript Files When Printing with /COPIES
When you use the /COPIES qualifier with a PostScript file, DCPS surrounds each
file with a PostScript ‘‘save’’ and ‘‘restore’’ to avoid exhausting virtual memory in
the printer.
However, there are infrequent cases when the print job aborts with an invalid
restore error message. If this occurs, use the /JOB_COUNT qualifier instead of
/COPIES.
2.19 Problems Using PAGE_LIMIT with /JOB_COUNT
If you use the PAGE_LIMIT parameter with the /JOB_COUNT qualifier, you
are apt to get undesired results. In particular, if your intent is to suppress some
initial pages of your job, DCPS will suppress them for the first copy of the job but
print all pages of subsequent job copies. If your intent is to suppress some of the
DCPS Restrictions 2–5
