I'd heard about some manufacturer putting a chip in printer refill
cartridges,  and then using copyright to keep aftermarket vendors from
making them.  I'd thought that it was one particular vendor doing that, 
but the guy I was talking to at a computer store today says to me
"they're all doing it".

Is this the case?  Anybody know?

If so,  maybe I'm looking for a used laser,  instead...
