Abstract: A schema is provided that logically represents a nodal hierarchy relating to execution of an application. The hierarchy includes multiple nodes, including one or more category nodes and one or more content nodes. An executable script is provided with the schema. The script may be associated with at least one node of the hierarchy. Each of multiple user inputs from the computing device are processed using the schema. The individual user inputs may be selective of nodes of the hierarchy. In response to processing each of multiple user inputs, user interface content is provided to the computing device. The user interface content for each user input corresponds to one of (i) one or more nodes, or (ii) a script content, generated as an output of an executed script that is associated with a selected node.

Abstract: A user requests a plurality of content feeds. Content associated with the content feeds is periodically retrieved and converted to a print format. Contents associated with the content feeds are stored in the print format. Indications corresponding to the content feeds are provided to a network connected printer and displayed on a user interface thereof, including an indication that new content is available in the print format.
