Best parallel card for Harmonie?

[vector <abuse@aol.com>]

Despite the FAQ's recommendation of using a serial-to-parallel converter 
for connecting to modern printers, I've decided to buy a parallel card 
instead.  They cost less and go faster; what else do I need to know?

Actually, what I'd like to know is WHICH card to get.  Assuming I get my 
IIgs's hard drive working soon, I'll install GS/OS and will consequently 
want to use Harmonie and Pointless for printing.  I see there are different 
drivers for Grappler cards, AII Parallel Interface and the like, but does 
one offer better results than another?  I've read that the AII Parallel 
Interface does a poor job of handling lots of data, but works with more 
programs (which is probably irrelevant under GS/OS).  I don't think having 
a buffered card matters anymore, since printers all come with large buffers 
these days.  Do some cards produce better-looking results, even on the same 
printer?

Is one card really "better" than another, for whatever reason?  Which?
