Hi folks,

Sorry it took so long for me to respond, but I've been waiting for a message
from someone who helped me set up my HP650c.  Here is her response:

Here is some other information that may help:

1) To get the HP650c to work, make a subdirectory called ps.devices under the
paint directory.  Create a file in the paint subdirectory with the name of the
postscript painter and the following information:

level: 1 or 2 (it doesn't seem to matter)
page width: 36
page height: 54
top margin: 0.5 (or whatever)
bottom margin 0.5 (or whatever)
left margin: 0.25 (or whatever)
right margin: 0.25 (ditto)
resolution: 300

2) The setcolor command in ps.map does not seem to work.  Also, I can't use
a user-defined colortable because I can't print out the 125 colors that
grass recognizes (that is the colortable command wants a value and I don't
know what colors the values relate to).

3) Although the HP650c reference manual tells you to set the language to
"automatic," this won't work.  You have to set the language to Postscript
instead.

4) The add.pagesize isn't working correctly with the HP650c.  The command
seems to work properly, but when I try to print the map out it disappears
into the plotter's black hole (that is it receives the information but never
prints anything out).  


I hope this helps, but could someone answer my original question:  How do
I control the raster color output since the setcolor command isn't working?
