OK, I originally started out with a DeskJet 500 with a built-in 16K of
cache...print speed didn't make too much of a difference between serial
and parallel.  Most of the time was spent waiting on the printer.

Later on, I got a DeskJet 550c and a 256K RAM cartridge that I set up 
to act as a print buffer in addition to the 80K that was already in 
the 550c.  With this setup, printing with the parallel card is definitely
faster...all of this was mostly done with AppleWorks GS/Harmonie/Pointless.

I haven't really tested it with AppleWorks, but I suppose I could.  Lately
I've just been printing to my LaserWriter IIg.  (Which is on an ethernet
network but I can access through localtalk with the IIGS and AppleWorks 
with the Imagewriter emulator downloaded via my FastPath router.)
