Printers are the text book examples of why device manufacturing shouldn't be left to big companies. You have tracking dots, spyware infestation, subscription for ink/toners, reporting of the cartridge as empty when you still have much left in it, refusal to print when unused color cartridges are empty, intentional bricking if 3rd party cartridges or ink is used, and utterly crappy firmware in general.
Inkjets require precision manufacturing. But assembling it or other types from components should be possible - like how desktops, mechanical keyboards, etc can be. We really need to ditch filthy mass market printers because DIY printers will be much better than anything they offer.
I do think it shoukd be left up to (potentially big) companies; however, we should put restrictions on e.g. ink cartrige compatibility, just like what the EU is trying for smartphones and messagin right now.
Both journalists and security experts have suggested that The Intercept's handling of the reporting, which included publishing the documents unredacted and including the printer tracking dots, was used to identify Winner as the leaker. In October 2020, The Intercept's co-founding editor Glenn Greenwald wrote that Winner had sent her documents to The Intercept's New York newsroom with no request that any specific journalist work on them. He called her exposure a "deeply embarrassing newsroom failure" resulting from "speed and recklessness" for which he was publicly blamed "despite having no role in it." He said editor-in-chief Betsy Reed "oversaw, edited and controlled that story." An internal review conducted by The Intercept into its handling of the document provided by Winner found that its "practices fell short of the standards to which we hold ourselves".
A technology that was made To Stop Criminals™ being used against a political whistleblower? Color me surprised! (thanks for sharing the link btw, didn't know about that)
Interesting. I remember reading a news article before 2017 stating that printers used to do this, but the practice has since ended because someone was able to prove they were doing it in the mid-2000s. At the time, I saw some people on Reddit claiming they just switched to a new, harder to detect method, and everyone was saying they were conspiracy theorists.
On wikipedia there's some suggestion that methods that involve intensity of toner/ink across a document could be used to uniquely identify a machine but no such methods are currently publicly known (at least as far as the Wikipedia article has been updated)
