The HP Color LaserJet Pro M451nw is a color laser printer for small offices and workgroups. It prints at up to 21 ppm in color and black, at 600 x 600 dpi, and connects over Wi-Fi, Ethernet or USB. High-yield toner cartridges keep running costs down, and HP's LaserJet line is known for durable duty cycles. Against newer color lasers it lacks automatic duplex printing and a touchscreen, and it is a larger, older design, so it suits buyers who want straightforward networked color printing rather than the latest features.

The HP Color LaserJet Pro M451nw (CE956A) is a desktop color laser printer. It prints at 600 x 600 dpi and up to 21 ppm in both color and black. It is aimed at small businesses and workgroups.
It connects by USB, Ethernet or Wi-Fi, so it can be used directly from one computer or shared over a network. It works with Windows and macOS. Mobile printing is supported through HP ePrint and Apple AirPrint, and AirPrint on iOS devices needs no additional drivers.
It uses HP 305A standard-yield and HP 305X high-yield black toner cartridges, plus HP 305A cartridges in cyan, magenta and yellow. The 305X black cartridge lowers the cost per page for high-volume printing. This model does not include automatic duplex printing.
