I would recommend not to use CUPS interface or CLI because maybe the GUI tool is overwritten the configuration file or something else.
Nah. Can't happen.
The 'GUI tool', as you refer to it, is nothing more or less than a user-friendly 'front-end' for the CUPS web interface, to make things as friendly and easy-to-use as possible for newbies. Any changes applied via the GUI are mirrored instantly in the main CUPS config files.....thus, there's no possibility of over-writing anything important.
The only reason Puppy (which I use) employs the web interface directly is simply to keep the OS as lightweight as possible; no point in having a GUI in addition to the web interface as well. Simply 'bookmark' the interface in the browser, and it's instantly accessible.....and most people usually have a browser open for something or another.
Every Linux distro employs the CUPS interface, but most of them 'hide' it as being confusing for beginners. It does, however, always work.....in the event of the GUI misbehaving. Which it occasionally does.
