SPP is the standard printer port, which is uni-directional only,
i.e., from PC to printer. It is basically the old Centronics standard.
Bi-directional in reference to the parallel port means data can flow
from the PC to the the printer, and from the printer to the PC. In
this context it has nothing to do with the print head operation.
I would assume that Normal is bi-directional at normal speed.
EPP and above are high speed bi-directional standards, which
your printer obviously aren't compatible with. My old HP 970
Deskjet was happy with EPP or ECP. ECP allows DMA transfers
to the parallel port.

Your printer should operate normally at the SPP setting. It just
wouldn't be able to send any status messages back to the printer
driver, such as low ink, paper jam, etc. If the paper advances
slightly with each head movement in either direction, the printer
is printing bi-directionally.



Ok, that would explain why there's no status message things for low ink,
etc.
or any related settings in the Properties tabs. So this bi-directional
thing
has nothing to do with the actual printing in both directions - printheads
go
across the paper and print, printheads come back and print - which is what
I
was trying to get it to do. Seems I had used the wrong term to describe
what
I was trying to do. :-)

Glad we got that sorted out. Same terms referring to different things can
be confusing. It looks like HP never gave general distribution to drivers
for your printer, for Win2k or XP. The drivers went to MS for inclusion
in the OSs. If you look up the Win2k driver for the 855c on the HP site,
they say the driver in Win2k is the latest one, and basically the same for
XP.
