If you are using the NIC that comes with the LQ500, you may have got a
flaky one.

If it is a bad one, it will reset at the slightest hiccup.

In such a case, better to switch to the parallel port and use an
external JetDirect box.

If you go this route you'll find when you take off the printer cover
they just hooked up a Centronix female plug onto a little NIC.  Just
unplug the Centronix cable and thread it through the alternate hole.
