I have the following code:

HTML

<table style="width: 100%">
    <tr>
        <th>
            teste
        </th>
    </tr>
</table>

JQUERY

    // Imprime a página
    window.print();
    // Redireciona página
    window.location = 'link';

Well the problem I have and the following. When printing on an A4 sheet the table occupies the entire screen correctly. But I put up a receipt and I want to print it on a non-fiscal printer, and it uses tape ends at 80mm, and the table is cut, as if it printed only half.

Well the solution I have in bundle, and have jQuery capture the width of the print sheet and change the css of the table.

Does anyone know how to do this? Or is there a better solution?

It is not yet possible to know print screen information in JS, so you can not capture the width of the print screen in jQuery.

Something you can do is use @media queries from CSS3 and make changes to the page according to the width / height of the print screen.

That may be enough.

(In% with% you must specify sheet widths.)

/* semelhante à 90mm */
@media print and (min-width: 80mm) {
    table {
        width: 350px;
    }
}

/* ... */
@media print and (min-width: 121mm) {
    table {
        width: 450px;
    }
}

/* +A5, A4, ... */
@media print and (min-width: 152mm) {
    table {
        width: 100%;
    }
}

You can declare how many min-width you want.
