As a happy 1200 owner (unless I'm printing graphics), I can tell you that I really really doubt USB will speed anything up. My iBook supports USB printing to this printer, and my full page 300 dpi graphics jobs take upwards of 45 minutes from pressing "OK, print" to paper coming out of the printer. It's just damn slow with graphics. Documents and the like are very fast, especially if you're dealing with a builtin font. Some webpage printouts can take upwards of 15 minutes, USB or parallel...
