This is done by selecting ppm as an output device:
   p.select ppm
When p.map is executed, a file called paint.ppm is created in your
home directory. It can then be transformed to a GIF or other
format using the ppm filters or the public domain tool, xv.

I would like to add to this dicussion.
The images obtained using the method, above have a somewhat coarse
resolution, coarser than when sending the output to a printer. 
Is there an easy way, to improve their resolution. If
not, does anyone know which part of the source code could be 
modified?
Thanks in advance.
