We have a Windows 7 home laptop that manages a homegroup. An HP printer is attached directly to the Windows 7 laptop. A Windows 7 laptop prints fine to the HP printer through a wireless connection to the homegroup. We added a Windows 8 laptop that printed fine at first, but now the printer disconnects regularly. We have to reboot the laptop to get it to print. (The printer is greyed out when it isn't connected) It appears that the Windows 8 laptop isn't connecting to the homegroup.) Any ideas are greatly appreciated.
