The biggest difference between 2D and 3D printers other than a dimension, is their complexity. People can make their own 3D printer, so trying to regulate it is absurd. With 2D printers, the governments just have the handful of printer manufacturers build the restrictions into the machine and it’s much harder for a random person to get around.
Typewriters were relied on to create unauthorized self-published books, brochures, leaflets, and magazines. As a result, Soviet authorities began imposing strict controls on typewriter distribution. Every typewriter had its own registration number, which allowed the KGB and other repressive organizations to determine the source of unauthorized documents. Each typewriter’s unique imprint made it possible to find out who wrote the paper and where it could be printed. In “Diaries: Uncensored,” Les Taniuk mentioned that there were typewriters for checks on which nothing “like that” could be typed, and two more – carefully hidden. Ukrainian writer and translator Halyna Kyrpa had to destroy her typewriter after a reprint of “Internationalism or Russification” by Ukrainian literary critic, social activist, and dissident Ivan Dziuba was typed on it. (In her interview with Chytomo, she said that she smashed the machine with hammers and threw it into a lake.)
2D printers are next.
2D printers were more than 15 years early https://www.pcworld.com/article/485139/counterfeit_money_on_color_laser_printers.html

I meant the pre-computer, monochrome type of 2D printer, the one referenced in “freedom of the press”, heh. Quick web search finds a prototype:

2D printers already have government mandated shit in them to prevent printing and scanning dollar bills.
