I am facing some issue with HP printer on my network. I had never face this issue before. But somehow it looks the printer fails to work on the network. The printer model is Photosmart C6180. It is connected on the network. There are 4 workstations on the network among which one is on Windows XP and other 3 are on 64bit version of Windows Vista. the XP system does not has any problem with the printer while in Vista the printer sometime appear and sometime it does not. It is very annoying. I have to enable and disable the network adapter and then after a few time it is visible.
