GtkPSproc is a GUI frontend for PSUTILS. It allows you to adjust all
programs to your printer type (for example, always sending the pages
in reverse order), to group two or more pages on a single sheet, to
print booklets, and to easily print in double-sided fashion. It is
designed to work from nearly all programs that call LPR, acting as an
intermediary between the program and LPR, but it can work alone, too.
