PostScript
4-79
MaxOpStack
integer
Maximum elements in the operand stack.
Legal value: Any integer greater than or equal to 75.
MaxPatternItem
integer
Maximum bytes occupied by a single cached pattern.
Legal value: Any integer between zero and half of RamSize.
MaxScreenItem
integer
Maximum bytes occupied by a single halftone screen.
Legal value: Any non-negative integer.
MaxSuperScreen
integer
Establishes an upper limit for the number of pixels in the supercell. Supercells
affect Type 1 and Type 2 halftones.
If MaxSuperScreen is set to zero, the use of supercells is prevented.
Legal value: Any integer between zero and half of RamSize.
MaxUPathItem
integer
Maximum bytes occupied by a single user path.
Legal value: Any integer between zero and half of RamSize.
MinFontCompress
integer
(Read-only) This value is always the value of MAXINTEGER.
PageCount
integer
(Read-only) This value is a running sum of the number of pages submitted by
the PostScript interpreter to the print engine for printing.
Note: This value is reset to 0 (zero) during PostScript initialization. Since
PostScript initialization by the printer cannot be known, we recommend querying
the value of PageCount at the beginning of a job and at the end of a job, and
then calculating the difference to determine how many pages are submitted to
the printer for a specific job.
This parameter is not valid for tracking pages between jobs.
UseOldcopypage
boolean
Legal values:
True
Indicates the copypage command is processed as defined in the
PostScript Level 2 description.
False
Indicates the copypage command is processed as defined in the
PostScript 3 description.
VMReclaim
integer
Legal values:
0
Enables automatic garbage collection
-1
Disables automatic garbage collection for local Virtual Memory
(VM)
-2
Disables automatic garbage collection for both local and global
VM
VMThreshold
integer
Frequency of automatic garbage collection, which occurs when the specified
number of bytes have been allocated since the previous collection.
Legal value: Any integer from 8192 to 500000, inclusive.
WaitTimeout
integer
Number of seconds the interpreter waits to receive additional characters from
the host before it terminates the current print job by executing a PostScript
emulation timeout error.
A value of 0 indicates an infinite timeout. WaitTimeout is initialized to the value
of the WaitTimeout system parameter at the beginning of each print job.
Legal value: Any non-negative integer.
