I have a Netgear WNDR4500 wireless router which allows me to print wirelessly to a printer connected to it via a USB cable. However, the software used to print to it only works for Windows and OS X. I've seen the question Printing to a printer attached to a network USB hub, and tried the instructions it gave using my router's IP address, but when I print a test page it says copying data then says printer is in use. In the printer queue window it says not connected. How can I print to the printer using Ubuntu? Thanks.
