I'm referring to using t= he multi-mirror DLP ic by Texas Instruments that used to be used in TVs. Th= e company in the following link uses the TI DLP chip to print directly, by = projection. No chopping up of an office laser printer is required. You'= ll need good knowledge of optics to get this working, but I consider this t= he best way to go.
