I have a Photosmart C309a connected to a tower via USB, The tower is running Windows 7. A second computer is an Acer laptop running windows 8, and is connected wirelessly via bluetooth built into the Acer. There is no printing problem printing from the tower, but documents sent from the laptop will commonly print the first two or three, and then the printer must be shut down and restarted for (laptop) printing to continue. Both computers are set for automatic updating for their respective operating systems. The latest HP driver(s) are also installed.
