Technical data

DCPS can print files that contain both text (ANSI, PCL, or Proprinter
data) and PostScript data. For example, users can print electronic mail
messages that contain PostScript files. The user submits the print job
without specifying any data type. The DECprint Supervisor software
begins printing the file as text and automatically recognizes the change to
PostScript, printing the file properly.
See Chapter 4 for information about customizing the printing system to
recognize and print the files generated by users at your site.
1.2 DECprint Supervisor Software Components
The DECprint Supervisor software includes the following components:
• A print symbiont, which processes print requests from OpenVMS print
queues assigned to the printer
• Queue management services, as described in Chapter 5
• Data type translators to translate non-PostScript files for printing on
PostScript devices
• A device control library for setup modules that affect the printing of files,
as described in Chapter 7
The DECprint Supervisor symbiont is used in place of the OpenVMS print
symbiont, PRTSMB. The software is distributed as executable image files, text,
and help files.
Figure 1–1 illustrates the process by which print jobs are produced on an
OpenVMS system and delivered to the printer.
