Comment on Brother accused of locking down third-party printer ink cartridges via forced firmware updates, removing older firmware versions from support portals

In case anyone was thinking this applies only to inkjet printers: no, it ONLY seems to apply to laser printers – the thing that Brother used to be known for. Where the article says “ink”, they mean “toner”. There is no ink in a laser printer.

Could this be anything related to government printer tracking requirements?

  I believe that only applies to ink jet. You can hardly make secret dots in B&W.

    There is something similar for B&W laser printing. Text is never 100% black, but rastered. You can digitally hide a whole lot of information in microraster on a page of printed text.

    Does “rastered” mean the image is mapped onto a very fine grid and each square is given a 0-100 value for intensity of ink? I looked it up, and it seemed like the squares are given a binary value, but this is nowhere near my wheelhouse and I’m honestly not sure I understood the Wikipedia page, let alone the references

    Wait, I thought that’s something that only color laser do with yellow toner…
