PURPOSE : A method for printing web data searched in the Internet is provided to enhance a convenience of a user by controlling a printing of standard web data being displayed on a web browser and performing the printing as a pre-set non-standard window output.CONSTITUTION : A user connects to a specific site or service which processes a real estate related business of the Internet using a host computer(S1). The user operates a web browser, searches/calls a web page for preparing an apartment leasing contract document(S2). The user inputs data with respect to contents with respect to the apartment and contract on input windows on the web page(S3). If the user inputs a printing command(S4), a microcomputer calls a printing form from a memory unit(S5) and combines the user input data with a corresponding output form(S6). Thus, web data with respect to an apartment leasing contract document are completed. The completed web data are transmitted through an output unit and a printing is performed(S7).? KIPO 2003
