I connected an Epson printer to the USB port of my AirPort Extreme Base Station but cannot get it to work. It shows properly in the Admin Utility Summary display on the configuration screen and in the USB Printers tab from the AirPort tab but cannot be seen from any computer on the network. Possibly relevant information is as follows: * AirPort firmware is version 5.6 * The AirPort does not provide DHCP or NAT services * The AirPort has a static IP address with appropriate entries for the router and DNS. * The DNS server has an entry (forward and reverse) for the AirPort. * The LAN port of the AirPort is connected to an ethernet switch with Mac, Windows, and UNIX computers. * Both Mac and Windows laptops connect by wireless. * All computers on the network (wired and wireless) can see each other and the Internet. * The printer, USB cable and printer software were connected directly from another computer and functioned properly. * Of the computers that need to access the printer: - The Macs run OS/X 10.3 - The Windows computers run XP sp2 or 2003 Server. Questions: * The AirPort IP address apparently refers to the WAN port (according to arp responses). Does the same address apply to WAN, LAN, and AirPort interfaces? Is there some way,or any need, to set a separate address for each interface? * When setting up the Windows TCP/IP Port Monitor which protocol should be used? If LPR protocol is used, what is the queue name? And should "Byte Counting" be enabled?
