Document printing techniques

摘要

We describe a portable paperless electronic printer for displaying a printed document on an electronic paper display. The paperless electronic printer includes an input to receive print data from an output of a printer driver of a computerised electronic device, a non-volatile electrophoretic display to provide an electronic paper display of stored said print data for a said document page to mimic said document page when printed on paper; and a processor coupled to said input, to non-volatile memory, and to said non-volatile electrophoretic display and configured to input said print data, to store said data derived from said print data in said non-volatile memory, and to provide to said non-volatile electrophoretic display data for displaying a said document page derived from said stored data.

主权项

1. A paperless electronic printer system for displaying a printed document on an electronic paper display, the system comprising:
a device that is arranged to run a document display management program; locate, by said document display management program, an application associated with said printed document; automatically invoke, by said document display management program, opening of said document on said device using said application associated with said printed document such that opening of said document is hidden from said user; generate, by said document display management program, print data in response to said automatic opening of said document, said print data print data comprising data for one or more document pages to be printed, said print data comprising an image of a said document page to be printed being scaled by said device based upon scaling data determined from a document previously printed by a user associated with the one or more document pages to be printed wherein the same scaling data is applied to the whole document; and a portable paperless electronic printer comprising: an input to receive said generated print data; non-volatile memory for storing said generated print data; a non-volatile reflective display to provide an electronic paper display of a document page of said stored generated print data; and a processor coupled to said inputs, to said non-volatile memory, and to said non-volatile reflective display and configured to input said generated print data, to store said generated print data in said non-volatile memory, to provide to said non-volatile reflective display data for displaying a said document page derived from said stored generated print data; wherein said automatic opening of said document is triggered by an automatic background synchronisation service to provide image data from said device to said portable paperless electronic printer.
