Input files containing PostScript may be specified on the command line. If none are given, then ps2fax will read from standard input.
By default, ps2fax will generate a 98 line/inch output document whose page width is 1728 pixels and page length is 297 mm (a standard A4 page at low resolution). Horizontal resolution is always 204 dpi. The -r option can be used to specifiy an alternate vertical resolution (typically 196 lpi for fine resolution). The page width and page length can be specified with the -w and -l options, respectively. Note that page width is specified in pixels, while page length is specified in millimeters.
The -o option is used to specify the name of the output file. If no filename is given, the output is placed in a file named ps.fax.
By default, output is compressed using the standard Group 3 1D encoding scheme, with EOL codes padded to byte boundaries. If the -2 option is specified, output is encoded with the optional Group 3 2D encoding scheme (EOL codes are still padded to byte boundaries). 1D encoding can also be explicitly specified with the -1 option.
The default environment includes support for the following Adobe Type 1 fonts:

Note that this is the same set of fonts supported by the DPS extension to the X server.
${SPOOL}/etc/dpsprinter.ps PostScript code read at startup for DPS
/usr/lib/DPS/default.dps_vm startup VM file for DPS
/usr/lib/DPS/outline Type 1 fonts for DPS
/usr/lib/DPS/prebuilt prebuilt versions of fonts for DPS
No prebuilt bitmap fonts are currently available. This would greatly improve legibility at low resolutions, as the rendering of outline fonts at 98 lpi is particularly poor.
