Yep.  Here's the info you need.  There is certainly missing info in
the SVR4 documentation and some bugs still lurking.  This info works
on an Apple laserwriter, QMS PS-810, and HP laserjetII with postscript
cartidge for sure.  Your mileage may vary with other postscript
printers.

Here's the scoop (do all this as root):

0) Be sure that your printer is connect to a SERIAL line and not a
parallel one.

1) Configure the printer queue as such:
	
	a) lpadmin -p {name of queue} -v /dev/tty01 -T PS -I PS
                                           ^ name of serial port you are using.
	b) lpadmin -d {name of queue} [optional, make this the default printer]

2) Create a text file (/tmp/foo) that looks like this:

Input types: postdown
Output types: PS
Printer types: PS
Printers: any
Filter type: fast
Command: /usr/lib/lp/postscript/postio -q
Options: PRINTER * = -L/dev/null

3) type the command : 
	lpfilter -f postio -F /tmp/foo

4) Enable and accept the printer:

	accept {name of queue}
	enable {name of queue}

5) just to be sure:

	lpshut
	/usr/lib/lpsched

6) To print a ascii file:

	lp -d {name of queue} filename  

  Try: lp /etc/passwd

7) To print a postscript file:

	lp -d {name of queue} -Tpostscript filename  

8) to print a troff file (via /usr/ucb/troff):

	lp -d {name of queue} -Ttroff file

This works fine for us.  Let me know if you have any problems.
