One other option is to configure a new printer as a "Raster File Export ADI". You'll get a *.bmp file. I've found that the background is black (not good) so when I import into Paint (don't have a fancier editor) I select to "Invert Colors".
This is if you're using an older version of AutoCad (i.e. 14). Above replies show later solutions.
PDF995 is a great solution also.
