yes, you are right. I have done that, but in general from my experience
of more than 20 years advocating for free software is that in general
there's no knowledge and just fear. The license file had more that 20
years and has no sense.

Said that, my question is still valid FMHO because I have not found in
any place how to fix a parameter in CUPS, or I didn't understood.

So, let me adapt my question. If I have a parameter, for instance a
paper size, or color or black and I, as a system administrator want to
fix it and not let the users to changed, how can I do it?

Thanks in advance,

Leopold
