DCPS Version 1.2 Information

This chapter describes the changes that are in Version 1.2 of the DECprint

Supervisor.

15.1 DCPS Version 1.2 Highlights

The following list provides a brief description of the signiﬁcant changes included

in DECprint Supervisor Version 1.2. You can ﬁnd more information for several of

these changes elsewhere in these release notes.

• DCPS Version 1.2 requires less memory and pageﬁle space. This is achieved

by allowing a supervisor process to control multiple print queues (run

‘‘multistreamed’’). This allows a system to have far fewer DCPS supervisor

processes, and thus alleviates memory and pageﬁle consumption.

• DCPS Version 1.2 reduces idle queue processor overhead by allowing

supervisor processes to control multiple print queues, thereby reducing the

number of supervisor processes and the overhead imposed by each.

• DCPS now supports printing to printers on an AppleTalk network from

OpenVMS Alpha systems.

• AppleTalk printer names may now be speciﬁed with 8-bit accented characters.

• The ANSI translator has been ﬁxed and no longer abnormally truncates lines

when printing with A4 page sizes in landscape orientation.

• When printing to serial- and LAT-connected printers, DCPS is less aggressive

on job startup. Previously, DCPS could cause a print job from a UNIX host or

LATSYM to abort if the job had completed on that host, but was still printing

at the printer. DCPS now waits for the printer to stop printing before it

begins the new job. A new DCPS logical name can be deﬁned to restore the

old behavior, if needed.

• Previous versions of DCPS could hang, especially on AppleTalk connected

printers, if a job name contained the ‘‘]’’ character. This problem is corrected

in this release.

• Under rare circumstances, DCPS V1.1 and V1.1A could exit with the

following message ‘‘%DCPS-F-INSEF, insufﬁcient event ﬂags’’. This problem

is corrected in this release.

• New system logical names are now recognized for changing DCPS modes and

behaviors to other than the defaults.

• The startup template command procedure, DCPS$STARTUP.TEMPLATE has

been updated to show how to conﬁgure the print supervisor for multistreamed

operation.
