Hi everybody,
I’m coming back with another problem I have since I upgraded from 22.04 to 24.04. I have a network Brother printer with scanner. I have no difficulties to print from my different devices, but it’s a real pane to scan documents, especially from my desktop. When I launch simple-scan, it keeps on searching a device without being able to find my Brother device.
Here is some command, if it can help you to provide some advices.

I tried to perform a diagnostic :

It never stopped ! I had to interrupt the process.
Any help would be appreciated.
