Wehave a MAC operating with OSX 10.4 and has a USB cable connected to a HP printer. I have a PC and I can print on this printer by switching USB cables. I also added a standard TC/IP port with the IP address of a USB wireless print server on my PC. I can easily assign the HP printer to the IP or USB port. If I assign it to the IP port and connect the print server to the HP printer with a USB cable, I can print wirelessly to the HP printer. I would like to find out how the MAC can have the HP printer assigned to this print server. Do you know if the MAC has a similar capability of switching printer ports?
