Ditherpunk 2 – beyond 1-bit
My understanding is that while "halftone" is an older term now, there was an in-between period where it meant any kind of dithering. Indeed, even on the page you linked you see people talking about Floyd-Steinberg and other kinds of dithering.
Thanks for the link, although the best I could find was this[1] old Java file that's completely uncommented. I was hoping for some textual documentation.

Sending commands to a Thermal Printer .NET MAUI
I've successfully used https://github.com/lukevp/ESC-POS-.NET for ESC/POS to control several brands of POS printers (but you won't use System.Drawing.Printing at all, you'll use ESC/POS to handle everything to the printer).

.NET Framework (4.6.2) and USB Receipt printing
I used Epson TM-T20III with https://github.com/lukevp/ESC-POS-.NET, works pretty well out of the box

Ditherpunk 2 – beyond 1-bit
My receipt printer library[0] uses dithering for images since the printers are black and white but fairly high resolution. It looks pretty decent [1], much better than a plain black and white conversion. I learned about dithering while implementing this library, and it’s a great technique! I originally implemented a black and white filter and then Floyd-steinberg dither natively in c# but then ended up using a library for it since we needed image transforms as well.
