Yup, yea, verily indeed.  It's nice to know that someone else can see
forest in spite of the trees.

The outline shape can't be copyrighted anyway, as we have all 
seen in the prior net postings.

and the bit map is the shape, and this cannot be copyrighted.  In addition
if you have a hard-disk version, you can read the font bitmaps off the
hard disk anyway.

Who knows, perhaps a desire to control the market, to call the shots, to
make money.  But probably because it would  violate  device independance,
the holy grail of printerdom.  Not all printers can do it, but the majority
can, and people need that ability.
