POSTSCRIPT

status and bytesavail return different results when output is compared among different implementations of PostScript, due to differences in the implementation of file I/O.

Path limits

The LaserWriter has a limit of 1500 path segments that can be defined in the current path. Any master that exceeds this limit generates a limitcheck error.

DocuPrint NPS uses a different scheme for representing paths in its internal memory than that used by the LaserWriter. Although the maximum number of path segments is larger than the LaserWriter’s (in other words, masters that print on the LaserWriter also print on DocuPrint NPS without limitcheck error), it is difficult to state the exact limit, due to the different algorithm for storing rendered shapes in DocuPrint NPS.

PostScript VM limits

DocuPrint simulates PostScript virtual memory (VM) limits (default=4 MBytes). When the PostScript VM limit is reached, it sends the PostScript error message “VMe=Error” to the “JOB AND ERROR MESSAGES” page. In rare cases when real VM runs out, the Printer Controller sequencer is automatically restarted and the job is held for either restart or cancellation by the operator.

SetCacheDevice

DocuPrint does not pad the bounding box of user-defined fonts. Emitters that depend on the PostScript interpreter for padding of the bounding box create PostScript masters that can result in blank pixels.

Device orientation and setscreen operator

Due to differences between the device coordinate systems in DocuPrint NPS and those in the LaserWriter or a typical desktop printer, the use of the setscreen operator produces different results between printers.
