HP Printers and Code Red

We are continuing to see some of our HP Printers dump memory when "code
red" hits their port 80.

We already know that on firmware ?.07.03 or greater we can:

Telnet to printer

type: ews-config: 0 

and this will disable port 80...

Does anyone have any ideas or suggestions on what can we do with the
older printers?  For instance a LaserJet 5000 with Firmware G.05.35 - 

Thanks in advance,
