Printing with CUPS

What do you mean? My question is, where to edit the hostname for the CUPS server.

I’m neither able to edit it from the configuration tab inside the addon settings nor can I add an addon which name would be hostname nor can I find the configuration file in the file system. Please offer a little more detailed solution.

Thank you
Benny

Hostnames for addon containers are autogenerated. I don’t think you can change it.
