Mac with Lion OS. Printer is HP 4500 (ethernet capable, but not wireless). Router is Linksys/Cisco. Mac sees web OK wirelessly (no ethernet port on Macbook). Printer is OK when USB attached. However, cannot get Mac to see printer via router/ethernet connection. Printer is attached to router via cable and cable has been checked. Have already tried using HP printer drivers and Apple drivers for the HP printer. Neither have fixed the problem. How do I make the Mac see the printer via the router. PS....have also reset the IP settings a few times on the printer. That did not work either. The IP address it assigns is 192.168.1.105 each time. Have tried to use that IP address in the "Location" box in the Mac Printer setup but that did not fix it. When using Mac to view the Printer web page, it times out.
