Question

When a user chooses “File > Print” on a browser such as Firefox or Internet Explorer, or clicks on a link that runs the below javascript

window.print();

Is there a way to conditionally check for this mode and disable SOME javascript.

I am trying to do this because I have a plugin that adds in its own custom markup for rounded borders and even in a print specific stylesheet I can not override the styling for these, I dont want the borders to appear when printing out the page.

EDIT: Unrelated to the plugin there are style changes done via javascript that is used to create a tabbed user interface and I have done print specific CSS to override the styling and it works fine when I use the Firefox web developer toolbar > CSS > Display CSS by Media type > Print.. but when I print it out it doesn’t work, the javascript takes over and changes the styling.. if I disable javascript completely then the printing obviously works fine again.

Thanks

You can do:

window.old_print=window.print
window.print=function() {
    alert('doing things');
    window.old_print();
}

but this will only catch calls to print() from inside the page javascript.

Did you try putting !important on print-specific stylesheet?
