Drywriter (idea)

I want to build a whiteboard printer. Functionally like the txtBOMBER, with dry-erase markers.
Fine Expo Clicks are small-diameter and could be closed without unloading from the printer.
Staggering the markers could allow for overlapping for a more subtle "scanline" artifact.
An Arduino controller could store a font and output simple text, or it could only speak bitmap and offload type rendering to a server. The latter would enable graphics and could lead to scan-and-copy functionality.
