I'm trying to get a window dump a graphing program I wrote using
'xwd' & 'xpr' in the following manner :
     1)  get application running and then type 'xwd -xy -out graf.scr'
         in another local window.
     2)  After getting 'cross-hair' cursor, I click on the window and
         wait for the 2 rapid beep, telling me xwd ius done.
     3)  type xpr -output graf.scr.ps -device ps < graf.scr
     4)  type lpr -Pps graf.scr.ps

I'm running this on a Sun 4/110 with a color monitor (/dev/cgfour0) and
trying to get it to print out on a postscript laser printer(apple laser
writer).   I can run 'xwud -in graf.scr' and the the correct image, but
when I send it to the laser write via lpr -Pps, I just get a black
rectangle where the image should be.  

Does anyone have any suggestions of what I am doing wrong?  Does this
process only work on B&W monitors?

Any help would be greatly appreciated,
Angus
