The method comprises the steps of receiving a printing request sent by a class service receiving terminal by using the printing request in a cloud server system, and analyzing JSON format character string data in the printing request, wherein the JSON format character string data comprise a printing data acquisition URL and parameters, a printing template identification ID, a printing client connection identification and printer setting information.
In step 250, the cloud server acquires data and converts the data into printing data in the form of the applied printing template, so as to acquire printer setting information. And sending the printing data and the printer setting information to a printing client in the computer equipment.
The cloud server calls a data conversion service, acquires URL and parameter loading printing original data according to the printing data, acquires printing template format content represented by an XML format according to a printing module identifier, analyzes the printing template format content through an XML analysis object, traverses the printing template content, finds out each data binding item in the template, and replaces the data binding item with a corresponding field value or a group of values in the printing original data. And obtaining the printing data expressed in the final XML format converted by the format of the applied printing template, and obtaining the printer setting information in the printing request.
And acquiring a WebSocket connection object of the printing client by calling a printing connection class service in the cloud service according to the printing client connection identifier in the printing request, sending printing data and printer setting information to the printing client through a connection object channel, and transmitting the printing data and the printer setting information by using a JSON format character string.
And step 260, the printing client in the computer equipment receives the printing data and the printer setting information sent by the cloud server, sets the target printer attribute, decodes the printing data and sends the decoded printing data to the target printer equipment for printing.
The method comprises the steps that a printing client in the computer equipment receives printing data and JSON (Java Server pages) format character strings sent by a cloud server through a WebSocket client program, analyzes printer setting information, sets a target printer name, sets an attribute value of the printer, and analyzes printing data content, wherein the printing data content comprises a printing content component marked by an XML (extensible markup language), each element and attribute of the printing data content are loaded through the XML analyzing component, and a printing command is circularly called and sent to the printer equipment for printing.
