Huh, to be honest I feel like I've only ever seen halftoning when printing onto paper -- I've never associated dithering with printing at all.
And the "linear dithering" you're describing, when I think of images in certain banknotes and passports or quality seals that I'd call "engraved", I've always assumed were hand-drawn by an artist.
But I like what you're describing and linking to, as a way to achieve that hand-drawn effect algorithmically, to include a directional texture element! Thanks for sharing.

Yep, sorry about my sloppy terminology. I always use "halftoning" and "dithering" interchangeably. Yet, notice that today's printers are often matrix-based, i.e., like a high-resolution binary screen, with a bit of ink smearing depending on the type of paper/plastic.

Maybe some are still drawn by hand, but most printed stuff is at some point dithered automatically (and a lot of critical information can be embedded on the dithering patterns).
