Even if they were stored as bitmaps, those bitmaps would be highly 
compressible in many different ways (RLE, edge-detect, ...).

And then, the resolution of those things wouldn't have to be the same 
resolution as the printer itself. For example, those bitmaps could be 
rendered at 100 or 150 dpi, and then use only the extra resolution for the 
purpose of dithering the picture. The purpose of having 300 or 600 dpi has 
been chiefly to avoid seeing the dots, and this is only because inkjet 
needs lots of dithering.
