Abstract: A computing device in accordance with an example includes a display surface. The device also includes a first sensor to determine a distance of a user from the device, a second sensor to determine an ambient brightness of the device, and a controller to automatically adjust a brightness of the display surface based on the distance of the user from the device and the ambient brightness.

Abstract: Systems and methods for printing a document over a network are described. The system may include an authentication code generation module coupled to a processor to receive a document to be printed from a user. Further, the authentication code generation module ascertains whether the document is confidential, based on a confidentiality determination criterion. On ascertaining that the document is confidential, an authentication code corresponding to the document is generated to provide print control to a predefined set of authorized users. The authentication code is provided to the predefined set of authorized users including the user.
