The postscript
driver class is used to produce output that is
acceptable to PostScript printers and to PC-based PostScript
interpreters such as Ghostscript. Continuing a long tradition,
PSPP's PostScript driver is configurable to the point of
absurdity.
There are actually two PostScript drivers. The first one, postscript, produces ordinary DSC-compliant PostScript output. The second one epsf, produces an Encapsulated PostScript file. The two drivers are otherwise identical in configuration and in operation.
The PostScript driver is described in further detail below.
