Hi
If you simply want to dump a file to the printer (PS or otherwise) here is
a small IDL program that does the job:
(without using the spawn procedure)
PRO print_file, filename, PORT=PORT
if n_elements(PORT) eq 0 then PORT='lpt1'
; *** read file into buffer
openr, unit_read, filename, /GET_LUN
fs = fstat(unit_read)
buffer=bytarr(fs.size)
readu, unit_read, buffer
close, unit_read, /all
free_lun, unit_read
print, 'sending ', fs.size, ' bytes to ', PORT
; *** write buffer to PORT
openw, unit_write, PORT, /GET_LUN
writeu, unit_write, buffer
close, unit_write
free_lun, unit_write
END
You set the print port using the keyword PORT='port name'. The default port
is 'lpt1' but it can be set to anything.

This is a great program. I just hacked XWINDOW.PRO and PS_FORM.PRO a little
bit to add print buttons which spawn PrintFile. PrintFile in turn spawns
GhostScript and sends the converted file to a non PS printer. This lets me
use all the great features of xwindow to create a predictable postscript
file, as well as printing the file directly to a non postscript printer.
This way I get an immediate hardcopy, and a saved file.I've never had
reliable results with other ways of dumping a plot to a printer without
alot of extra code in my plotting programs.
yippee.
