This reflects a lack of technical understanding of the subject. The proposal is not enforceable, as there is no control over the end user’s networking stack. E.g. you can't actually rely on "3D printers that report themselves". The law makers need our help and some technical consultation.
The manufacturer can simply require that all prints go through their proprietary software, or better, cloud service for validation before the printer will accept them.
The person proposing this, and/or their staff certainly knows this.
It's okay, we just need a new tax to cover the mandatory sim chips that will need to be installed in compliant printers (which will not be permitted to be operated in metal buildings or basements, of course.)
