And this is a shame, although I would agree the image on screen may not
benefit a great deal from the increased colours it would be nice to be
able to print out to a printer that can use 24 bit colour and I'm not
sure we can do this if we can't display them ( I'm not sure we can do
this even if we could display them).
IIRC RWAP are doing something about Epson high colour/resolution
drivers.
Of course I could be talking a lot of bull hear, if so feel free to say
so - I can take it (;-)
