I have been searching and searching for days how to get this printer to work with linux. Now it is not connected to any computers but directly to the my router via RJ45. I found another post that helped me with my situation but I figured it out. So I would like to share what I have found...

Configuring the NEC 1800N w/ Gnome Printing on Ubuntu
Open up Printing
Then click on Add a Printer
Select Network Printer
Drop down to Unix Printer(LPD)
Host:192.9.9.9 (whatever the ip address of the printer is on your network)
Queue: /printers/queue1

Click Forward
Manufacturer select NEC
Model: Superscript 1800
Driver: hpijs

Then click Apply

You should then see SuperScript-1800 Ready
Double click that
Goto Printer->Properties
Print a Test Page

Only problem I have with this I have to hit the go button on the printer because it keeps telling load Tray 2 with A4.


Hopefully this was helpful...
