Network printer not appearing in Router network graphic

[#1]

I cannot see my network printer in the Home Network graphic of my TG582N router.
The printer has a fixed IP of 192.158.1.55 and is connected directly to the router by Cat5e cable.
My IP camera also has a fixed IP 192.168.1.10 and is cable connected and does appear!
To all intents and purposes ethport 2 has nothing attached to it.
Any ideas folk?

Have you tried connecting the printer to the other ports and have you tried connecting perhaps your camera to that same port?
If you haven't I'd do that as the next step

Hi Adam,
Just tried that - no difference. Printer still does not show up. I suppose that proves that the ports are all live?
The printer software (HP) finds the ink levels OK, and the printer prints as per usual, so comms are going both ways.

All sorted now!
Removed fixed IP address from the printer and then fixed the router assigned IP address on the router.
Simples!

Glad that's sorted, we'll make a mental note for future reference.
