Which kernel versions are you using? There was a problem in 2.4.18 with
plip:
http://www.ussg.iu.edu/hypermail/linux/kernel/0202.3/0113.html
which I ran into once. The symptom was that machines with 2.4.18 could
transmit, but not listen properly. I.e. always 100% loss.

If it is a one-way error in the cable, reversing the cable should throw
some light on that...
I found that plip was very cpu intensive - even once I got the EPP/ECP
settings in the bios to agree with the kernel options. That took a bit
of work, as it did not seem to autodetect very well.
IIRC I ended up setting the bios to EPP and created this in
/etc/modutils/parport:
options parport_pc io=0x378
[I know: this should be the default IO port. But I must have added it in for a
reason. It's a loooong time ago though]
If everything else fails, you could fall back to a null-modem cable and
ppp. Or apt-zip - if that is applicable for an initial install (never
used it myself).
