Supplemental Operators
This section explains PostScript emulation supplemental operators in detail. These
supplemental operators are extensions to the standard PostScript language. For each
supplemental operator, the exact syntax is listed, as well as the values returned on the
stack and possible error messages.
Tips for PostScript emulation command extensions:
•
Set operators are effective until the end of a job. At the end of a job, these
values return to their default values.
•
Setdefault operators do not become effective until the end of a job. However,
the value may be queried immediately.
•
Unless otherwise noted, all of these operators are located in the statusdict
dictionary.
•
In userdict, #copies is initialized at the beginning of each job to the number
of copies selected either by PJL or from the printer operator panel.
To determine which operators your printer supports, see Table C-1 on page C-1.
