Abstract: In one example of the disclosure, an encrypted document and an encryption key for decrypting the encrypted document are received from a computer. Presence data for a printer is received via a first wireless network. A user instruction to print the encrypted document at the printer is received. A credential is received from the printer via the first wireless network, where the credential for communication with the printer via a second wireless network with greater bandwidth than the first wireless network. The encrypted document and the encryption key are sent to the printer, where the printer is to utilize the encryption key to decrypt the encrypted document and is to print the document following decryption.

Abstract: A method includes sensing, with a sensor, a distance of a user from a display of a computing device. The method further includes comparing, with the computing device, the sensed distance to a threshold distance, and determining, with the computing device, whether the user is present at the display based at least in part on the comparison.
