Subject: usb-tethered verizon/netgear airpack + ethernet printer

Is it possible to use the ethernet port of a laptop to feed a printer
while the laptop is connected to the Internet via a usb-tethered
verizon/netgear airpack 791L?

Network manager appears unable to find the printer.

I guess that should be possible. However this could be tricky.
Usually the verizon devices put you into 192.168.1.0/24 network. This is
also the network most home routers put you in. It might be possible that
those two network collide.
Most likely you also get your network settings via dhcp. Here also the two
different network collide. Most likely the later connection will overwrite
the first and screw things up.
I would recommend setting up one network manually making sure that they
have non colliding networks.

Thanks, Henning.  The solution I used was:

- configure the printer for ip address 192.168.3.201
  with gateway 192.168.3.1
- add connection 192.168.3.1 in network manager
- plug the ethernet cable from the printer into the laptop ethernet port

In theory, it should be. You may need:
 * A "cross-over" cable. If you're not using an ethernet switch between 
 the two devices, then a cross-over cable will avoid both devices 
 talking on the same pins.
 * A DHCP server on the laptop. The easiest method is to configure both 
 the printer and the laptop's ethernet port with static IP addresses 
 (192.168.5.1 and 192.168.5.2 should work (192.168.X.Y is a private 
 range and 192.168.5.Y probably won't be used by, say, the internet 
 connect)).
