If you were to do the following:
% p.select painter=ppm
% p.map (include a numbered grid for a raster file, scaled to 5inches)
% ppmtopgm ~/paint.ppm | pgmtops | lpr -P<PostScript printer>
^^^^^^^
This would probably be 'pnmtops -noturn' for
most people, but the folks at my site aren't
too good at software updates.
does it cut off the bottom line of the grid? I tried reporting this
as a bug once, but I don't know if the PIC was able to reproduce
what I was reporting.
