Your HP printer provides a number of features that make it accessible for people with disabilities.
The printer software is accessible for users with visual impairments or low vision through the use of
your operating system’s accessibility options and features. It also supports most assistive technology
such as screen readers, Braille readers, and voice-to-text applications. For users who are color blind,
colored buttons and tabs used in the software and on the HP printer have simple text or icon labels
that convey the appropriate action.
For users with mobility impairments, the printer software functions can be executed through
keyboard commands. The software also supports Windows accessibility options such as StickyKeys,
ToggleKeys, FilterKeys, and MouseKeys. The printer doors, buttons, paper trays, and paper guides
can be operated by users with limited strength and reach.
