RE: filmscanners: pixels, printer dots, etc
Thank you for that very informative post. There is one issue I believe
warrants clarification, IMO.

The driver should/does not just "toss" the data, it should use it
intelligently and algorithmically to arrive at the required dither pattern.
If you had a sequence of data 0010 and wanted to cut that data by four,
would you make the result a 0 or a 1? Well, the way it should do it is take
into consideration surrounding data, and intelligently arrive at the result.
So, though the data set IS reduced in your example, the data is used to
arrive at the resultant dithering, not just tossed out.
