I have purchased an HP C4580 wireless printer. My main computer is a Macbook Pro and I connect to the internet via a wireless modem/router I have managed to get the printer operating in both USB wired and wireless mode over the modem/router with my Macbook Pro running OSX I need to run and print from some windows programs so I have Windows 7 running on the Macbook also via Parallels. The printer will work in Windows if the printer is connected to the Macbook via USB but I cannot get the wireless to work in Windows. When running the HP install for it I get the following message: The PC and the printer are connected to different networks(237DB2A87D and 66616B65). They must be connected to the same network. This can happen when you use the manufacturer's default network name (SSID) and another nearby network is using the same name. I also have tried to connect to the printer via another Vista desktop connected wirelessly to the modem/router and get the same error message so I dont think its got to do with the fact I have a Macbook, OXS, Parallels etc. Can anyone help me with this as I am totally lost.
