how to suppress HPLIP device status message
 

When I am running my HP printer with HPLIP a small window opens in the top-left corner of the desktop (see screenshot).
This is annoying both because it hides my bookmarks and because it cycles through its messages for each copy of the print job.
Is there any way of suppressing this message? Given that it is obvious the printing is happening, I don't see any advantage to it.

I am running 19.1 Cinnamon on a Lenovo ThinkCentre tower.

Thanks

Open the HPLIP GUI (hp-toolbox on the command line), go to Configure-->Preferences-->System Tray Icon, and check "Always Hide."

Let us know how it works. I found the setting but have not tested it.:)

I have my own print queue manager, so those messages drove me crazy.

In addition to what @frankbell notes, you need to set notifications to "Errors only". See screenshot.

I'm on KDE, so it may look different on your system.

Sorry to be so slow getting back to this.

I was fascinated to see the hp-toolbox command. Unfortunately it did not work: I tried "Always Hide" with "None", and then with "Errors Only", and then with "Errors and Warnings", but none of them produced results. I then tried "Hide when Inactive" in the same combinations without result.
I still have a laptop that dual-boots, so I installed the driver on Windows, and tried there--but although a GUI opened, I saw no option for the Tray Icon.

I should have said: it is an HP Laserjet Pro M106w with HPLIP-3.19.5 version installed.
