I don't know what you're doing but simple back-of-the-envelope
calculations will tell you that the difference between 7 & 8 bits is
at most 100% (each byte is sent in ascii as a pair of hex digits
which doubles its size). 5-10 times difference is way off beam, so
something else is involved.
papd is slow is because it is layered on ATP which is slow. Most
people don't notice because most of the time is spent in the RIP (and
PS RIPs are at their worst with v large pixmaps). Like the difference
between using a fileserver over AppleTalk vis ASIP. If you're
spooling, however, you'd really notice the difference.
It's been several years since I worked in this area (OPI servers),
but is there some reason why you can't send 8-bit data over TCP/IP
using the lpr protocol?
