Abstract: A user token management system in a client device on a network comprises an obtaining module, a web controller and a processing module. The obtaining module obtains a user token from a database in response to a retrieving request for retrieving authorization of a web service provider on the network. The web controller transmits an authenticating request for authenticating the user token to the web service provider and receives an authentication result authenticating the user token. The processing module deletes the user token from the database when that user token is not authenticated by the web service provider.

Abstract: A standalone printer includes a configuration module, a screen, a process module, and a print module. The configuration module can arrange two digital images in a print layout. The screen is configured to display a preview of the print layout with the two digital images. The process module is configured to decode the print layout of the two digital images into a raster image along a decoding orientation. The print module is configured to print the raster image along the decoding orientation. The process module is configured to stream partial raster image to the print module when decoding the print layout. The printer module is configured to print received partial raster image.
