I may buy a servo system which I will connect to the
(centronics) printer port on a PC/AT.  From the recent
article on lost interrupts in printer drivers I am
assuming a high level of black art from these drivers.

My question is this:  what kind of data rate may I assume
if my servo system can take an infinite amount of data,
ie. no buffer-full waiting.   Another related question is
what is the failure at high data rates: pc hangup,
lost characters, etc.  (Neither of these is acceptable from
a servo system.)

Any help is appreciated.
