## Long description

HP 777 printhead is a replacement printhead designed for HP DesignJet Z6 Pro and Z9+ Pro large-format inkjet printers. With compact physical dimensions of 146.8×131.4×27.7 mm, this printhead restores nozzle performance to support high-resolution technical and photographic output. Compatible with professional reprography, CAD drawings and high-quality graphic prints, the part is supplied as an individual unit intended to return a printer to factory-level nozzle operation and consistent colour rendering.

Restoring or replacing a worn printhead improves line sharpness, edge definition and tonal gradation in high-resolution maps, technical drawings and photographic prints. The compact form factor simplifies installation and reduces downtime when servicing the printer.
