The print certainly looks nicer/cleaner on a higher resolution device. Of course, for laserprinters it is important to be able to produce grays, which is not an issue on an lcd screen (but possibly on an eink device)

You are confusing dpi (
dots per inch) with ppi (
pixels per inch).
Laserprinters (and film imagesetters, for that matter) produce on/off dots, not pixels with shades of grey. When reproducing continuous tone images (like photographs) to get the same effect as 16-greys 166ppi eink screen you'd need a 600+dpi laser printer.
Of course, if you're not producing continuous tone images, the higher resolution is more important. Personally, I'd rather have a black/white 600dpi eInk screen than a 16-grey 166dpi eInk screen, but that's not an option yet.
