The HP Standard Keyboards represent a design extension of the successful Easy Access keyboards. These keyboards introduce expanded configurability by allowing the keyboard to sit upon the desk at either zero-degree (flat), 6-degree or 12-degree slope through the use of the keyboards tilt legs. Hence you receive a wider range of configurable slope options to maximize your comfort when using these keyboards.The HP Standard keyboards also simplify System Administration tasks as no additional reprogramming or redirector software is required to be maintained or supported with these keyboards. The keyboard software device drivers are an integral part of the client operating system.
