Postscript device

[Jean Boivin]

Dear GRASS-users,

How do I tell GRASS to use my Laser4 600dpi postscript
printer? By default, ps.map is using 75dpi.

I tried putting a file in $GISBASE/etc/paint/ps.devices
looking like this:
2
8.5
11.0
0.5
0.5
0.25
0.25
600

Which are the margins, etc., and the number of pixel per inch.
BUT, using ps.map, I've got the following error:
PS-PAINT: PostScript painter "laser4" selected.
ERROR: PSmap: do_scale(): shouldn't happen

Any ideas??
thank -> Jean.
