A network printing system and printing method

Abstract

The invention discloses a network printing server. The network print server includes: a print job storage configured to store a print job list; a printing device registration unit configured to respond to a VPN connection request of the printing device including VPN parameters, and establish a VPN connection with the printing device through the VPN server, Registering the printing device, and creating a print job list corresponding to the printing device in the print job storage, the VPN parameters include the VPN server IP address, the domain name of the printing device, wherein the domain name of the printing device is bound to the hardware id of the printing device; and a print job management unit configured to receive a print request from the computing device, add a print job item to the print job list of the requested printing device, the print job item includes a print job ID and a print job content. The print job management unit is further configured to receive a request from a printing device to download a print job, and send the requested print job to the printing device. The invention also discloses a network printing device and a corresponding printing method and system.

Description

Technical field [0001] The present invention relates to network printing technology, in particular to a network printing system and printing method. Background technique [0002] The printer is a common device in the office environment, mainly used to print the computer processing results on the relevant media. At present, network printing within a local area network has become a common way. Some organizations (such as companies and schools) even set up a dedicated printer server. Users install the client driver of the printer on their computer, so that the Files (such as photos, documents, etc.) are printed out on the printer managed by the printer server. Since computers, printers, and printer servers are all located in the local area network, which is a closed system for the organization, it is easy to perform secure management and printing of print jobs. [0003] However, printing users may be outside the corporate LAN in many cases. For example, when a user on a business tr...

Problems solved by technology

However, in these printing methods, because the printer server is arranged outside the local area network of the organization (such as a hotel), files and messages sent between the outside of the organization and the inside of the organization via the Internet are often intercepted by various security devices, resulting in this way that requires a lot of effort from the administrator to fix the problem

Moreover, some printer servers obtain IP addresses through NAT, etc., but this IP address will change due to changes in the network environment, and it is difficult for users to determine the current available IP address of the printer server
