  I'm having a problem with printing to an ESI brick, and was wondering
  if anyone out there could shed some light on the subject.

  In past kernels (1.2.x and 1.3.<58?) I was able to print fine to this
  brick. The brick in question is an Extended systems MPX model #
  ESI-2810. It has a Laser-jet 4 hanging off the first parallel port, and
  is using the TP port for it's network connection.

  Now, when I try to print a file to this printer (currently kernel
  2.0.10), it hangs after about the first 2.5 pages, and never completes
  the job. Looking at netstat reveals that the connection is in the
  ESTABLISHED state with about 20k-30k in the SendQ and -1 in the
  RecieveQ.

  I don't know enough about it (or have enough time) to study the output
  of tcpdump to see what's going on. Does anybody know what I could try,
  or what I should look for in a tcpdump output?

Does Emulex produce this device by any chance?  I just ran into a bug in the
TCP/IP implementation in the Emulex NetJet with precisely these symptoms.  It
has been reported and acknowledged by Emulex, but they can't give any timeframe
for a fix nor even commit to the fix being in the next firmware release.  I am
not particularly amused by their response.
