The ps driver produces publication-quality PostScript output but only for a limited selection of glyphs. The driver provides two devices: the ps device for black-and-white plots, and the psc device for color plots.
This driver is unicode enabled, and PostScript Type I fonts are used. This driver has no external library dependencies. However, a drawback is that text layout is limited to left-to-right scripts (i.e., languages with complex text layout are not supported). Furthermore, Type I fonts have an extremely limited selection of glyphs compared to, e.g., TrueType fonts (see the section called “The psttf driver”). For this reason, Hershey fonts are used for drawing symbols by default for this device driver, unless specified otherwise using the driver options.
The available driver options are:
text: Use PostScript text (0|1); default 1
color: Use color (0|1); default 1
hrshsym: Use Hershey fonts for symbols (0|1); default 1
