They may be printing semiconductors, but will never have even remotely close to the density that photolithography give you. I'm involved in both designing semi's and laserprinters and know this claim is NOT a threat to FCS.
printing semiconductors has already been done for several years, and that MIT professor is going to IPO the company known as ePaper or eInk. However, the applications are vastly different and more on the MEMS side. FCS does not have the technical capabilities to compete in these fields.
