Abstract: Wireless data communication between two devices is described. In an example implementation, an image frame displayed on a display unit of a transmitting device is captured by a camera of a receiving device, where the image frame comprises text characters converted from binary data bits based on a text mapping table. The text characters in the captured image frame are converted to the binary data bits based on the text mapping table by the receiving device.

Abstract: In one example, a method is disclosed in which a key is generated in a client device when a print job is triggered at the client device. The key and the print job are provided to a printing device. Further, a first thumbnail of a page of the print job is generated in the client device. The page is determined as a function of the key. A first secure image is generated in the client device using the key and the first thumbnail. The first secure image is shared with the printing device. The first secure image is verified by the printing device using the provided key and then the print job is released upon successful verification.

Abstract: In one example of the disclosure, a capabilities message is received from each of a set of computing devices, the capabilities message indicative of whether the computing device can provide printable content. Capabilities data, indicative of printable content provision capabilities for each of the set of computing devices, is stored. A display of printable content capabilities for the set of computing devices is caused. Responsive to a user selection of a first computing device that can provide printable content, printable content is obtained from the first computing device and printing of the printable content is caused.

Abstract: A technique includes, in an electronic device, in response to a print job, identifying active printers; and in the electronic device, prioritizing the identified active printers to process the print job based at least in part on a location for the electronic device and statuses associated with the printers.
