It would make a degree of sense that it's the P**l***c adaptor then given
that the network traffic looks good so the only thing that could really
mangle it is the 232 end and maybe the timings are just about good enough
running on the local loopback device to stop it going to sleep (or any
other odd things it may do). We have some FDTI ones knocking around at
work so I should be able to nab one of those for a bit (oddly enough it's
the FDTI ones that always seem to misbehave under Windows...). I should
also have the bits to build the Dragon's Drivewire adaptor in the near
future so that will give another angle on it for me to try.

I have CUPS running on my main Linux box so I'd probably just have the Rpi
forward requests to that then onto one of the rack of printers hanging of
that.

Rgs,
