Can't make the printer default?

[CadeW]

I already tried this popular fix > http://pcsolutions-alternative.blogspot.com/2014/02/unable-to-set-default-printer-lets.html

...but it doesn't work. My regedit don't have a "Device" on it. Look >

I already uninstall then reinstall the printer. Restart and all that can't make it default. Printer is plugged via USB and it's on. I also still have ink. When I click on the printer's Properties, the Model Number and Description are "Unavailable"

Can anyone help?

Windows 7 64bit
HP 2510 All-in-one printer.

Try reinstalling the printer driver package.
