The very first thing I would do in this situation is to perform a full
factory reset, then re-enter all the settings.  If settings don't
"stick" it could be either a corrupt config file, or a scrambled firmware.

Alternatively, you can setup a DHCP reservation for the printer so it
always gets the same IP address.

If that doesn't work, reflash the firmware. There might be a new version
out for your AirRouter.  If not, check your model number over at
OpenWRT.  Take Russell S. advice and go OpenWRT:

1. Openwrt is superior to most factory firmwares.  I converted my
Netgear WNDR3700 ages ago.  Now running BARRIER BREAKER (14.07, r42625)

2. you'd be up and running in 15-30 minutes with OpenWRT instead of
wrestling a day or 2 with buggy and proprietary factory firmware.

3. I have 2 HP printers with static IPs on my Netgear router network.
It took less than 1 minute to tell OpenWRT to change the DHCP as well as
to give those IPs "human readable" names via DNS.
