> You know, it might not be such a bad idea to make a printer-bot ala a RepRap that allowed you to put any writing instrument you wanted into the cross-hairs and slowly draw out your documents like a plotter. The ink might be "cheaper" that way and it would be kind of fun to watch 8 of them on your wall draw your documents concurrently.

This is a neat idea -- for bonus points you could have it understand MetaFont, which is designed around an idealized pen.
