Print orders using printer paging

Principle: everyone window.print () function can print Web pages, but usually we do not want to print all the content of the entire page. At this point, you can use JS to retrieve the contents of the original entire page, and the content of the area (Div) to be printed, then run the function, replace the page with only the contents of the Div, execute the print () function, and then restore the page.
Control paging only requires this statement: <div style= "page-break-before:always;" ><BR/></div>
