From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Epiphany/1.6.3 Description of problem: Unlike other Gnome apps, the "OK" button does not save a config for a printer. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Load system-config-printer 2. Double-click printer to edit it 3. Change the default tray 4. Do not click Cancel to discard the changes, instead click OK 5. Print a test page - wrong tray! 6. Close the original Printer configuration window. Am prompted to save changes. Additional info: I think this behaviour is a bit confusing, and non-standard.
Yes, the whole thing needs rewriting. I have been saying this for ages. cf. https://www.redhat.com/archives/fedora-devel-list/2005-February/msg00040.html Someone needs to come up with a DESIGN though.
There's nothing wrong with the existing design. The only thing that needs modifying is that changes are saved when you click the OK button, rather than when you close the main window. I'll read that link soon though.
Making the change you suggest would be *more* confusing: already you need to click 'Apply' to apply changes such as deleting a printer and setting a default printer, which are single-click operations. While it remains as broken as the design originally was, it would be far less confusing to keep the behaviour broadly the same as well. It will all change when the program is redesigned.
"Apply" is normally misused anyway". Often you see a user click Apply then OK, just in case.
