I would like to add another ink jet printer which performs better than
ip4000.
BTW, I like ip4000 but there is no reason to buy the same printer.
The ip4000 is not in production anymore. The heads likely are and the
mp780, the only fax inkjet all in one should still be in production.
All newer models are going to to offer smaller ink drops. I should say
5pl and 1pl drops rather than the ip4000's 5pl and 2pl.
So the new printers, while i've not seen them enough to judge, are
likely going to offer better shading than the ip4000. Peformance, as
in speed, might be reduced for color photos because simply you have the
choice of the same large brush or an even smaller one. But you might
prefer the look of having more shades rather than finer dots or both.
Or you might want faster text printing. As Michael said we don't know
what you want that's better.
