- They use "microfine" toner but tone is still toner. I have extensive
- experience with a 1016dpi plain-paper typesetter and its hard to
- distinguish from a 600dpi quality laser engine (it uses microfine
- toner).
-
- HP's RET (which stands for Resolution Ehancement Technology and is a
- registered trademark like FinePrint (Apple's technology)) will
- attempt to place particles more precisely than 600dpi on the 4M but
- the results will be very, very difficult to distinguish from
- "standard" 600dpi on the same machine.
-
- Only a photographic process, with a laser exposing film, is precise
- enough to give noticeably better results than 600dpi.
