Error "Job held for authentication" when printing from Ubuntu 20.04

I connected an HP printer on USB port of my box (freebox delta) with samba shared printer enabled.

I tried to add the printer from cups or from printer configuration but can't print anything with both conf. Always get "Job held for authentication" error in "/var/log/cups/error_log" even with no authentication set.

However :

• printing works perfectly when printing from my smartphone connected by WiFi to the network.
• printing works perfectly when I plug the printer directly to my laptop.

My conf :

• Kubuntu 20.04 and 19.10.
• Printer is an HP LaserJet 1160.

I've not found anything working from the net.

Please help me!
Thanks.
