Method and system for printing from web applications, a corresponding computer program and a corresponding computer-readable storage means
A method and a system for printing from web applications, as well as a corresponding computer program and a corresponding computer-readable storage means, are described. The method and system are particularly useful for improving the print functionality of web applications; e.g., by enabling printout of additional formats. It is proposed to provide on web pages a print option that can be controlled via data input means of a terminal. Activation of the print option causes a server executing the web application to send the data to be printed to a designated print server to start a print process on the print server, and to send the data generated by the print process from the print server to a network printer or to the terminal.
1. A method for printing from a web application,
said web application being started in a browser of a terminal, being executed on a first server, generating, in response to a user input into the terminal, a content and providing, in the browser, a web page containing a content, the web application further providing a print option for printing the content,
the print option being operable via input means of the terminal,
the terminal having installed a plug-in, which is called from the browser in response of receipt of data in a pre-defined format,
the method comprising the steps of:
causing, by activating the print option, the web application to send data in the pre-defined format to the terminal,
calling the plug-in in response of the receipt of the data in the pre-defined format,
accessing, by means of the plug-in, a second server to obtain configuration data, describing a configuration of the second server,
providing, by the plug-in on the terminal, a menu for controlling the printing,
providing the first server with at least a part of the configuration data and with data inputted into the menu, causing the first server to send data of the content to be printed to the second server based on the configuration data and on the data inputted into the menu,
starting a print process on the second server for generating print data, and
sending the print data from the second server to at least one of a network printer, a fax printer and the terminal.
2. The method of claim 1 , wherein the first server is an application server.

10. The method of claim 9 , wherein the data entered or detected via the provided menu comprise
information about the printer on which the print data are to be printed, and
an address of the designated print server to which the at least one portion of the data sent to the application server together with the data of the content to be printed is sent.
11. The method of claim 9 , wherein the at least one portion of the data entered via the menu is sent to the first server by using the browser.
12. The method of claim 11 , wherein the at least one portion of the data entered via the menu is sent to the first server as an HTTP request.
13. The method of claim 9 , wherein the at least one portion of the data sent to the first server together with the data of the content to be printed is sent to the second server via a conventional web transmission link.

at least one first server executing a web application,
at least one second server,
at least one terminal cooperating with the at least one first server and with the at least one second server, the at least one terminal has at least one plug-in installed on it, which is called from the browser in response of receipt of data in a pre-defined format, wherein the web application is called in a browser on the at least one terminal, generates, in response to user input into the terminal, a content and provides, in the browser, a web page containing a content and further provides a print option for printing the content, the print option being controllable via data input means provided on the at least one terminal,
wherein activation of the print option causes the web application to send data in the pre-defined format to the at least one terminal,
the plug-in is called in response of the receipt of the data in the pre-defined format,
the at least one terminal accesses, by means of the plug-in, the at least one second server to obtain configuration data, describing a configuration of the at least one second server,
