Design of the DECprint Common Printer Supervisor for VMS System

DECprint Printing Services software controls a variety of printer features for a wide range of printers. It supports several different page description languages, handles multiple media simultaneously, and uses different I/O interconnections and communication protocols. Operating within the VMS printing environment, it implements a large number of user-specified options to the PRINT command. DECprint Printing Services functions as the supervisor in the VMS printing system for all PostScript printers supplied by Digital. The common printer supervisor has an especially flexible internal structure and processing method to serve complex printing environments. [The DECprint paper starts here.]
