Eunieprunie,
We got my printer to work!!! I just finished a chat with an HP Instant Support Professional, Marquis K. I will tell you exactly what he had me do to get it to work. Hopefully it will work for you, too.
For starters, he directed me to do this:
"Let us now power cycle the printer by following steps below: 1. Turn off the printer and disconnect all cables from the printer (power,USB,network,phone). 2. Wait for a minute, then press and hold the Power button for 30 seconds. 3. Then connect only the power cable and turn on the printer. (Note: The power cord should be connected to the wall outlet and that wall outlet should not be providing power to multiple devices.) NOTE: This releases the static charges/flea power that keeps on accumulating in the power circuit of the printer over time and by normal power off/on, it does not get cleared"
This did not solve my problem alone, but I figured that it must have helped, because everything else he told me to do, was stuff I had already done. He had me check in the Control Panel under Devices and Printers, and check to see if an icon for the printer was there. it was. Then he asked if there was an error message on the icon. There was not. THen, he had me open a document and try to print it. Nothing happened.
Next, he had me touch the wrench icon on the printer touch screen, select Tools, then Printer Quality report. That worked.
After that, he had me go back to the Control Panel, select Programs, then Programs and Features, and find the HP Photosmart 6520 software. Three things were listed there, the basic driver package, help, and some product improvement something. He had me righ-click on each one and uninstall. As I uninstalled the driver, it instructed me to unplug the USB. Do not reconnect it until instructed to do so by the software.
Next, he had me reinstall the driver, file name: PS6520_1315.exe. He gave me a link, but I had already downloaded it from a previous try, so once I verified that the filename was the same, I installed that. Here's the link, just in case you need it:

Once we verified that my driver was the correct file, I double-clicked to install. You will come to a window that shows the HP recommended software for the installation and gives you an option to customize. Just hit Next to install the recommended software. It will then ask if you want to connect wirelessly or via USB. Select USB. This is also the point where you plug the USB cord back into your computer.Once it connects, it will ask you to print a test picture. Do it. Mine printed. Then, it will ask you some preference questions and you'll be done.
Now, open a document and try to print. I really hope that this works for you as it did for me.
Cheers,
Grace
