The new line of HP PageWide office printers is powered by the biggest improvement in printhead technology in years. The secret sauce is called High Definition Nozzle Architecture, or HDNA, and it stands to considerably improve productivity in the office. 

The magic comes from a complete rethinking of how ink is transferred to the page. In a traditional printer, the printhead moves back and forth across the page, depositing ink line by line while slowly advancing the paper with the aid of a mechanical roller. 

HP Inc. took this idea and turned it on its head. HDNA printheads don’t move at all. Instead, they feature a printhead that is the same width as the page with tens of thousands of fixed nozzles spanning the entire printhead – a total of 2400 nozzles per inch of page width. With HDNA, only the page moves, quickly being fed through the printer as ink is deposited across the entire page all at once. The result: HDNA powers not just best-in-class print quality but also accelerated speeds.
