	I've been printing over the ethernet onto a Tektronix 4693DX and getting
nice results.  First I run:
		/usr/lib/print/k93print file.rgb > tmpfile

Then I merely catenate tmpfile into the device associated with the printer. 
For example, if the printer is hooked into serial port 4:
		cat tmpfile > /dev/ttyd4

Hope this helps you.
