Do photo printing services (or existing self-publishing services) assess content for copyright infringements? Or do they pass it off with "you assert that you have the rights to print this content"? I suspect something along those lines could work for this too. If the service can be 'blind' to what is being collected (eg, all happens on the user's device and the central printer just takes the collected file). Automated version of a local printshop that just prints whatever you give them.
