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.
2.20 Printers with Auto-Sensing Features
Many printers can sense the data type of a print job. Such printers allow you to
specify how and whether the auto-sensing feature is enabled, per interconnect
channel, through the front panel.
For most printers that offer this feature, the DECprint Supervisor software works
properly when the printer is set to ‘‘PostScript’’ mode, or to ‘‘Automatic’’ mode.
You must set such printers to operate in one of these modes before starting the
DCPS queues. The DCPS software does not operate properly if the printer is set
to ‘‘PCL’’ mode.
See Chapter 4 and the DECprint Supervisor for OpenVMS System Manager’s
Guide for additional information.
2.21 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.
2.22 Cannot Start Queue for PrintServer Printer
Because of a CPAP protocol bug in some versions of DIGITAL PrintServer
Software, DCPS symbionts can be given a badly formatted packet in response to
a resource query. The bad packet prevents a symbiont from starting.
The problem is triggered by loading enough resources to require more than one
packet describing the resources loaded to be returned. The suggested workaround
is to load fewer resources. Empirical testing has found the limit to be 7 fonts.
This problem is fixed in version S5.0-29 and later of the PrintServer Software.
