Just a few days ago, I realized, the best thing to update somebody else's code, would be to print it out and take it to bed with me, so I can read the source without starring into that lamp (the monitor). I also could make notes with a pen, like placing the line number next to a function call (pointing to the function definition), etc.

Problem was, that the printout would have been over a hundred pages. Too expensive and feels like a waste of resources.

Then I remembered dot-matrix printers and checked out the market. They go about EUR200+ these days. Sadly, the one I'd liked (DIN A3 format, so to be able to print out long lines of code without wrapping, with 4 colors for some basic syntax highlite) are in the EUR1000 range.

My text-editor on the Amiga (in the 90's) would have a special print utility, that would allow to format the text (source code) in a way to fit as much text on the paper as possible, by choosing a smaller font, having multiple columns, etc.

Interestingly, nothing similar seems in production, these days.

So, ideally there'd be an affordable dot-matrix color printer, without a fixed line length (set it in the driver), and some pleasing monotype font for coders (including special chars like function arrows) as one of its internal charsets along with a utility I described above. My eyes would love it!
