gs-esp-x 8.15.4.dfsg.1-0ubuntu1 (amd64 binary) in ubuntu gutsy

 Ghostscript is used for PostScript preview and printing. Usually as
 a back-end to a program such as ghostview, it can display postscript
 documents in an X11 environment.
 .
 Furthermore, it can render PostScript files as graphics to be printed
 on non-PostScript printers. Supported printers include common
 dot-matrix, inkjet and laser models.
 .
 This package contains the Ghostscript output device for X11. It is in
 a separate package to allow the main package (gs-esp) to be installed
 on X-less servers.
 .
 This version of gs is a fork of GNU Ghostscript with updated drivers
 and patches, intended mostly for use with the Common UNIX Printing
 System (CUPS) from Easy Software Products (www.easysw.com). The
 ESP Ghostscript homepage is available at:
