Under Debian Buster, I am looking for a solution to print with CUPS but without having to provide the password each time. Under Windows, I just had to enter the credentials for the desired printer port and when printing it no longer asked for a password.

How to do the same in Debian?

For information, for the sake of traceability, each user is authenticated by an account created on the CUPS server and our printers are not directly visible. You have to go through the CUPS server redirected by the /etc/cups/client.conf file of each client with the ServerName directive and pre-populated when printed by the User directive.
