Under Printers and Scanners, I see the following devices:
- Fax
- HP PSC 750
- Microsoft Print to PDF
- Microsoft XPX Document Writer
- OneNote
No matter which one I click on, I am presented with the same two buttons: Open queue and Manage. No matter which button I press, nothing happens. If I double-click the device itself, nothing happens.
On the other hand, under Bluetooth & other devices, there is a Devices and printers which mysteriously can't be found if I type in either printers or devices. If I click on that, I get a Devices and Printers panel showing the same devices as above. I can actually double-click HP PSC 750 and scan something.
Why are there two different panels showing the same devices?
In Windows 10, is one more authoritative than the other?
Is the Printers and Scanners window supposed to be unresponsive?
BACKGROUND
I am on Windows 10 Pro 64-bit. In case the following might be relevant, I spent the last week trying to get the HP PSC 750 recognized on this new Windows 10 laptop. I went to their Universal Print Driver for Windows and installed the USB Driver, which enabled printing but not scanning. Finally, I enabled Receive updates for other Microsoft products... under Advanced options for Windows updates and initiated an update. That enabled printing and scanning after unplugging and replugging the USB cable. I'm not sure if any of these steps might have caused the Printers and Scanners panel to be unresponsive.
