I am trying to get a deskjet 612c on my network using a lantronix box.
I can telnet into it and set configurations, I can reboot the server
remotely, I can even use the "test port <port #>" command and it will
print but when I send a print job from any machine on the network I
get "spooling" then it changes to Printing- Printer Error.  this
particular lantronix box was just being used successfully on an HP
8000 just a few days ago on another network so I know it works.  I
have followed the instructions to the letter per, lantronix
instructions on their web page using EzyWebCon.
my network consists of an NTWS IP 167.6.72.171, NT Server IP
167.6.72.173, and the lantronix adapter IP 167.6.72.163
subnet mask 255.255.255.0
No routers.

here is my lantronix server config.
