Prevent upload for some users

Hello all,

I'm looking for a way to prevent users from uploading files so that I have a canonical set of files (hopefully editable by the admin), but users can only print / pause / etc., but cannot replace these files.

If this doesn't exist, which is what I suspect, is this doable from a plugin?

Thank you in advance

It's certainly possible to write a plugin that would restrict some users in this and many other ways. How many printers do you have? Is this a printer farm or 3D printing company?
