Description
Technical Field
The invention belongs to the technical field of cloud printing, and particularly relates to a cloud printing method and cloud printing equipment.
Background
At present, a plurality of printers which can be wirelessly or wiredly connected to a local area network through WIFI exist in the market, and some types of printers in the printers can only realize local area network printing, namely, a user computer or a mobile phone and the printer need to be connected to the same local area network, and professional printing driving software of a manufacturer needs to be used on the computer or the mobile phone, so that the printing function is realized in the same local area network through a printing protocol. Such lan printing generally does not support cloud printing or remote printing, and if a user leaves the lan, the printer cannot be controlled to print.
In addition, some types of network printers have already realized the cloud printing or remote printing function, and the general flow of realizing this function is:
1. and setting the printer to be connected to a wireless network, and accessing a cloud server of a manufacturer for registration.
2. The user accesses the cloud server of the manufacturer through software tools such as app and the like and is bound with the printer.
3. And the user sends the document to be printed to a cloud server of the manufacturer.
4. The cloud server converts the document into printer identification data and then sends the printer identification data to the printer bound by the user.
5. The printer prints according to the received data.
Such as Google Cloud Print, enables remote Cloud printing inside the printer system. It relies on the fact that the printer already supports google cloudprint, most domestic printers, lower hardware configured printers cannot. Meanwhile, GoogleCloudPrint cannot be used domestically, and a universal printer driving mode is adopted, so that the printing quality is low, part of printing modes cannot be met (margin-free and double-sided printing and the like), the printing delay is high, and the printing speed is low.

When the data is transmitted to the printer of the user, the data occupies a large bandwidth resource of the server and the user, and particularly, when the printing is in a peak period and the network is crowded, the printing time of the user is long, the printing is stopped in the printing process, and the problems of printing failure and the like can be caused seriously.
2. Network printers of different manufacturers need to install software tools of the corresponding manufacturers. If a plurality of wireless printers from different manufacturers are accessed in a local area network, when a user selects a printer, the user needs to switch between different software tools, which causes great confusion to the user.
3. After the network printers of different manufacturers are replaced, if a user wants to perform cloud printing, the user needs to download the software tool of a new manufacturer again, and perform operations such as binding the printers again, which brings inconvenience to the user.
