The HP Printing Voice Assistant is an accessibility accessory that helps people with visual or dexterity impairments operate supported HP LaserJet Enterprise printers and MFPs. The compact keypad connects to the printer and lets users move through the control panel with physical Previous, OK and Next buttons, plus Home, Back and Start keys, or simply speak voice commands to run printer functions. A Screen Reader button reads out what is on the control panel, and a Quick Access button jumps straight to accessibility settings such as high contrast, inverted colours and screen zoom. Volume buttons and a 3.5mm headset jack keep audio private in a busy office. It measures just 54 x 98 x 16 mm and weighs about 50g, and works with a wide range of HP Color LaserJet Enterprise and Managed models.
