My router has a usb port. Can I plug in my printer so the other computers on my router can print from the printer?
No unless your printer is network-enabled & it has its own IP address. i_XpUser
That is a wan port on the router for usb internet modems. You can only use it for that. Get a network print server [little box] with usb printer ports and then connect it to the lan and you will be able to print to it from any station. Imagine the power if you knew how to internet search
Actually some routers were sold with a standard usb port and these were configured for hard/flash drives: http://kbserver.netgear.com/kb_web_...
