Where do you get printable discs? Amazon?
I don’t get them from Amazon because often, when they’re not sold by Amazon (and for specialized discs like these they are not sold by Amazon the vast majority of the time), they are sold by 3rd party sellers which repackage faulty or used stock and sell it as new.
