Hi Andy -
We were having many probs with IDL postscript files, also. Our solution
was to send a raster file to the printer instead of a postscript file.
Will the Tek printer handle anything besides PS? Can you send it a "Sun
Raster File", gif, tiff, or something else that IDL can produce? I can
help out if this is something you want to pursue.

I handle this a little differently. I use device coordinates to set
everything up.
In the following example, plot the contour of IMAGE(INX,INY).
----- start
set_plot,'PS'
; set the orientation dependent on x and y box sizes
if iny ge inx then begin ; use portrait mode
x = inx/float(iny) * 8.0
device,/inch,xsize=x,ysize=8.0,bits_per_pixel=8,xoffset=(8.5 -x)/2., $
yoffset=1.5,/color,filename = file
endif else begin ; use landscape mode
y = iny/float(inx) * 8.0
device,/inch,xsize=8.0,ysize=y,bits_per_pixel=8,yoffset=9.5, $
xoffset=(8.5-y)/2.,/color,filename = file,/landscape
endelse
!p.thick=2
!p.position=[0,0,1,1]
; now plot the contour
contour,image,/noerase,xstyle=5,ystyle=5,position=[0,0,1,1], /normal
device, /close
----- end
This works with our Tektronics Phaser color printer.
Good Luck,
