I actually saw a new Lexmark at the store the other day that claimed to do 4800x1200 DPI (it's the Z65, I believe) and the samples looked phenomenal. Not that I have any particular interest in all of this. I've just always liked Lexmark, as they tended to produce the only not-outrageously-expensive PostScript compliant printers on the market. That's not as true as it once was, though.
