The HP Color LaserJet Enterprise M856dn is a high-volume A3 colour laser printer built for large offices and print-heavy departments, part of HP's Enterprise M856 series aimed squarely at replacing a shared departmental copier/printer rather than sitting on an individual desk. The "dn" in its model name indicates built-in automatic duplex printing and network connectivity as standard. This catalog listing is brief on further detail -- no print speed, resolution, or paper capacity figures are given here -- so anyone wanting exact specifications should check HP's own M856dn datasheet. Machines in this class are typically bought by IT departments provisioning shared print infrastructure for busy corporate floors rather than individual users.
