	As you know i posted the same question last week. Here is
	the responses i get from the net.  THANKS  to all of you.

	I had some news since last week. Canon France tell me that 
	the lpb4 and the lbp8 II are compatible and use the same 
	language (CaPsl)(That mean the same escapes code).

	So gs ... -DEVICE=lbp8 should work with a printcap like this:

	lp|lpb4|CANON LBP4 laser printer:\
          :lp=/dev/ttya:sp=/usr/spool/lpd:lf=/dev/console:sh:1:\
	  :ms=cs8,-onlcr:

	I am waiting for the programmers manual of this printer and
	if necessary i shall rewrite a driver for this lp.

	By the way,  you spoke about a postscript card which cost ~$500 ?!
	Where ? I found oonly one at $1200.
