	The total bps is 58.6K for the mux as a whole.  ie: 3 at 19.2 or 6 at
	9.6 or 2 at 19.2 and 2 at 9.6.

	The queueing should be no problem.  If you haven't setup the spooler
	look in the sysadmin manual page 5-44.  Watch out for step 7 it 
	should read:
nohup sleep 20000000 < /dev/tty0p2 &
stty -parenb -enqak cs8 9600 -cstop -clocal ixon opost onlcr tab3 < /dev/tty0p2

I'm not sure about paper out.
below is my inittab and ll of /dev/lp.

If this help your welcome.
