Depends on whether your definition of resolution is based on the number of 
black only dots that can be placed in a straight line, or the number of grays 
that can be mixed for a given area... a contone printer at 300 dpi offers a 
lot more "resolution" for eight bit per channel images than an on-off printer 
like an inkjet at 720 (which is Epson's one bit resolution), even if the 720 
printer offers slightly sharper text, which is defined by the one bit 
resolution. Epson's advanced resolution numbers are similarly only obtainable 
as extra dithering levels, not actual black and white resolution.
