HP B5L47-67019 US English keyboard kit is a replacement physical keyboard for supported HP printer control panels. HP identifies it for c and z models, making it a service part for restoring the physical keyboard function on those configurations.
The US English layout distinguishes this kit from keyboard options for other regions. The physical keyboard works through the printer control panel, providing a direct way to enter text and commands. HP lists language-specific overlays as separate parts, so this item is the keyboard kit itself.
