Hello @gheorghe !

A more briefly headline is more effective.
You can write your further information in the post.

This is not a networking issue, I'll move the topic.

There are more power USB cables in the world than those for data.
Those for data are thicker and good ones have ferrite beads at the end.
You may check some more.

You also may check if the printer has a good power connection.
