Printing technology manufacturer Memjet has filed a lawsuit accusing hardware manufacturer Hewlett-Packard of patent infringement. The lawsuit alleges that Hewlett-Packard has infringed upon eight Memjet patents related to their page-wide "waterfall" printing technology. Hewlett-Packard is incorporating technology similar to Memjet’s in its entire line of 2D printers, and their new highly anticipated full-color Multi Jet Fusion 3D printer.
