masters using cexec. Usage of cexec is typically hidden by the encryption of eexec.

LaserWriter defines other entries in the System Dictionary that are specific to its device characteristics, such as extra operators that deal with the hard disk. Such operators are not part of the standard as defined in the PostScript Language Reference Manual, second edition, and are not implemented on DocuPrint NPS.

User Dict

User dictionary entries that are implemented include:

cleardictstact

{countdictstack 2 sub {end}repeat}

startpage

Prints a startup page

DocuPrint implements print-level commands provided by the client print command. PostScript-level print commands are ignored.

The following operators, which are specific to the LaserWriter implementation of PostScript, are defined with null functionality in DocuPrint NPS.
