Usage: $program FILE
Tries to produce a version of the PostScript FILE to print in manual
Duplex.
Options:
-h, --help display this help and exit
-v, --version display version information and exit
-q, --quiet don't print informational messages
-o, --output=FILE save result in FILE. If FILE is \`-', send to stdout
-n, --no-fix don't call fixps to fix PS problems in FILE
-f, --front output only the front pages (recto) on the regular
tray
-b, --back output only the back pages (verso) on the manual
feed tray
Produced output is meant for PS level 2 printers which don't support
Duplex printing, but support Manual Feed. Once the first set of pages
is printed (odd pages), manual feed is asked: introduce the odd pages
to print the even pages on the other side.
Because there is usually a short time out for manually fed jobs, you
should really be next to the printer. If ever the time out expired,
use the option -b to send only the missing part.
Environment variables FIXPS, PSSELECT and PSSET, if defined, are used
to find the tools.
