After a bad paper jam, Anne's computer won't print anything to her printer. She can print a test page from the printer itself, though. She went to "Devices and Printers" and saw a warning that there were problems detected with the Synaptics HID device. Leo says that's actually her trackpad. Then she had a warning message that said that "Windows has stopped this device because it has reported problems." This could be related to the Synaptics failure. Leo thinks she may have some hardware failure on the motherboard.
Before leaping to that confusion, Leo suggests uninstalling and reinstalling the printer through Control Panel. She doesn't need to use the software that she got with the printer, the computer should auto detect the driver and download it when she adds it. If not, she can go to the printer manufacturer's website, in this case hp.com, to get the drivers. She could also try plugging the printer into a different USB port and see if another one works. If that doesn't fix it, then this could be a larger issue with the USB hub of the computer.
Lastly, Leo suggests looking at the Device Manager. She can right click on "My Computer" and select "Properties." Click the "Device Manager" tab, and make sure there's no red X's or yellow triangles. Those indicate driver issues. If that's the case, she'll want to right click them, delete them, and then restart Windows and Windows should reinstall the drivers.
