1. A network print server, comprising:
a print task memory configured to store a print task list; a printing device registration unit configured to establish, in response to a request of a printing device, a network connection with the printing device, register the printing device and create in the print task memory a print task list corresponding to the printing device; and a print task management unit configured to receive a print request from a computing device and add a print task entry in the print task list of the requested printing device, the print task entry comprising a print task ID and print task content; and a two-dimensional code encoding unit, wherein the print task management unit is further configured to determine whether an indicator exists in the print request indicative of the print content comprising a two-dimensional code, and if so, the two-dimensional code encoding unit is configured to encode a URL intended to be converted to a two-dimensional code into a two-dimensional code bit stream and store it as part of the print task. |
