You can set size in @page media before calling window.print

var css = '@page { size: 50mm 50mm; }',
    head = document.head || document.getElementsByTagName('head')[0],
    style = document.createElement('style');

style.type = 'text/css';
style.media = 'print';

if (style.styleSheet){
  style.styleSheet.cssText = css;
} else {
  style.appendChild(document.createTextNode(css));
}

head.appendChild(style);

window.print();
