I would suggest you ask a few other users before accepting this casual put-down.

Note the use of lj+.  I believe that the ELAN product supports both the lj and
the lj+.  I would also like to get a better definition of what "prints just
fine" means.  It seems odd that ELAN and at least one other company would
spend a fair amount of effort on support of this printer if AT&T supported
it in the standard DWB distribution.

This appears to be a marvelous example of using an apparently relevant example
to try and get people to accept what are probably false conclusions.  Bill
Rieken may be wasted in the computer field when he has such promise as a
politician.

A few points that readers might want to consider:

	1) Why is the comparison not made to AT&T's DWB?  Does it support
	   PIC on the lj or lj+?

	2) The example chosen may well be close to the worst case for the
	   printer.  I suspect that ellipses and arcs have to be drawn point
	   by point while other simpler shapes can use higher level commands.

	3) What are "Space Shuttle graphics"?  It sounds impressive, but it
	   is rather hard to tell exactly what is being described.  I have seen
	   the ELAN product do a nice job of printing Mac generated graphics
	   on a lj (a copy of Escher's waterfall picture).

I have no connection with ELAN.  Ken Greer (the owner) used to work here at
Amdahl as a consultant.  This allowed me to see some of the results of ELAN's
package even though we do not use it.
