4.18 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.
4.19 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.
4.20 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.
4.21 Problems Using PAGE_LIMIT with /JOB_COUNT
If you use the PAGE_LIMIT parameter with the /JOB_COUNT qualifier, you may
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
trailing pages of your job, DCPS will suppress them for the first copy of the job
and omit subsequent job copies.
If you want multiple copies of your job with some pages suppressed, issue the
PRINT command the desired number of times rather than using the /JOB_
COUNT qualifier.
4.22 Setting I/O Buffers Too Small May Produce OPCOM Errors
If the size of the I/O buffers (set by the SYSGEN parameter MAXBUF) is too
small, the print queue will be stopped and the following message will be displayed
to OPCOM:
%SYSTEM-E-EXQUOTA, process quota exceeded
If this error occurs, increase the value of the SYSGEN parameter MAXBUF.
