Any clue? Sometimes works, sometimes don’t.

MAC is : e0:bb:9e:00:68:23

Strange enough, after 10 minutes, worked:

Likely the signal is not good, the printer does not respond nor acknowledge, the printer has a ip conflict.

That is what is possible from what I get from your logs.

When it happens again can you try to manually restart the printer?

Some devices don't handle outtages very well, so they hang on a broken handshake and don't understand they need to reconnect.

If it still happens can you try to restart dhcp? /etc/init.d/dnsmasq restart use this as cli command.

Could it be a sleep mode on the printer?

After some tests it seems the Randomized BSSID is the culprit. No more delay to connect. Let’s see if this solves the issue once for all.
