TEK 4693DX and SGI 4D/20

[Gregory Fedor]

I just installed the Tektronix 4693DX color printer on a SGI 4D/20 and have
run into a roadblock.  The TEK tests out okay, and I used the LPTOOL to 
install the 4693DX printer driver (filter?).  I was under the assumption that
*.rgb files could be sent to the printer directly i.e. lp -d<printer> <file.rgb>

The filter is calculating some sort of magic number to determine if the file
is an image file or not.  If it thinks it is it logs an error message about
the magic number and aborts the print.

QUESTION: 1) Is there anything else I need to do as far as setting things up?
          2) What's the best way to get an RGB image sent to this printer?

Thanks in advance...
