libgs9-common 9.56.1~dfsg1-0ubuntu4 (amd64 binary) in ubuntu lunar

 GPL Ghostscript is used for PostScript/PDF preview and printing.
 Usually as a back-end to a program such as ghostview,
 it can display PostScript and PDF documents in an X11 environment.
 .
 This package provides common architecture-independent files
 needed by the GPL Ghostscript library.
 .
 By default, GPL Ghostscript uses a font from the fonts-droid package
 to approximate glyphs in PDFs
 for which the requested CJK TrueType font is missing.
 If the fonts-droid package is not installed,
 these glyphs will be rendered as bullets.
