How to print a redirected page?

Using the print() JavaScript function is not possible without some tricks.

One alternative you could do is to load the page you want to print using the $.load() method of JQuery, save all the contents of the current page to some variable, set page contents with $.load() , and use the print() to print this new content, finally, to return the content of the original page.

The print() method only prints what is on the screen, not an external content. So you need to bring the external content to the current screen, print it, and return the original content.

Something like this:

var original = $("html").html(); //pega todo o conteudo original da pagina.
var pagina;
$(pagina).load("url-da-pagina", function() {
    $("html").html(pagina); //vamos pegar todo o conteudo da nova pagina
    window.print(); //imprimi
    $("html").html(original); //retorna conteudo original
});
