I use the 'import' command from the ImageMagick suite of command line
graphics utilities.  If you use a command like

  import -colorspace GRAY -window root -frame pgm:- | lpr

then this tells import to grab the entire contents of the screen in grayscale
format and then write it to standard output in PGM format.  The ImageMagick
man page says that it can produce Postscript directly, but I don't actually
remember why I am using PGM output instead.  ImageMagick supports a very
long list of output formats.  If you know the X11 window id of the window
you want to print, you can specify that to the '-window' option instead of
'root'.  Alternately, you can leave out the '-window' option altogether
and 'import' will display a graphical cursor that you can use to select
the window you want to print.

Hope this helps.
