Welcome to the HP Community --

If you have already tried all the first parts,

Go to section Windows - Reset HP Smart Application

================== =====================

- Printer Application - HP Smart – Windows -- Check / Reset -

Start

Reminder

It is important that every device is using the latest version of the HP Smart app for that device type.

Check / Update >> Every device (computer(s) and mobile) where HP Smart is installed should be running the latest version of the HP Smart application available for that device platform (Operating System / Version).

AND

The printer and device (computer, tablet, phone) where HP Smart is running should be on the same network.

That might be enough…

Stop if everything is now working.

Next,

Restart Everything, including the router that controls your network

That might be enough (at least short term) -- check...

Stop if everything is now working.

Next,

Windows

 Check / Run Windows Updates > Install any pending updates

Next,

If not previously completed,

Restart everything, including the router that controls your network.

Can’t stand it?  Consider:  Restart computer(s) and printer.

No Joy?

Thanks for this, but unfortunately it behaves the same after doing all the steps. It does work on my iPhone. I deleted HP Smart from my phone and same behavior on my desktop. Any folders or registry entries that need to be deleted?

@Herr1976 

You are welcome.

Unfortunate - I would think that something the combination of steps would have kicked it free.

Registry?

Sure, possibly.

I stopped giving out  advice for editing the Windows Registry years ago.

Personal Choice.
