Method and system for printing documents from a portable device

摘要

One embodiment provides a system for facilitating document printing from a portable device. During operation, the system receives a document at a server. Next, the system generates a document optical code corresponding to the document. Subsequently, the system communicates the document optical code to the portable device, thereby allowing the portable device to display the document optical code to a scanning mechanism associated with a printer, Next, the system receives a request, indicating the optical code, from the printer. Subsequently, the system retrieves the document in response to the request, and sends the document to the printer.

主权项

1. A computer-implemented method for facilitating document printing from a portable device, wherein the computer includes a processor, the method comprising:
receiving a document at a server; generating a document optical code corresponding to the document, wherein the document optical code comprises a document fingerprint, and wherein the document fingerprint comprises one or more numerical values that are mapped to one or more subsets of document features; communicating the document optical code to the portable device; receiving, from the portable device, the document optical code, and a printer identifier of a printer which does not have a scanning mechanism, wherein the printer identifier of the printer is a printer optical code which does not encode document information and which encodes access information for the printer; retrieving the document based on the document fingerprint included in the document optical code; identifying the printer based on the received printer identifier; and sending the document corresponding to the document optical code to the identified printer to allow the document to be printed by the identified printer.
