CUPS printserver enforce print settings
I want to enforce the default printer settings of CUPS clients because some users in my network don't have the patience to check their printer settings. For example I have a profile which has the defaults set as duplex in color with an A4 format. But the user and application can override this. Which sometimes happens. I want these profiles to be absolute and unchangeable. I haven't found a way to do this yet.
So to clarify again. I want to have a few profiles with printer defaults which can't be overridden by the user or application. This needs to be configured at the server side, not the client. An open profile will be included as well with the freedom to change the settings. The others are locked.
I hope someone can point me in the right direction for this one, I've searched for hours but I haven't found anything useful yet. There also seems to be a lack of community support for this since I can't find any official and sizable CUPS community.
