The relevance to the button doing nothing, is the button on the page
that if script is enabled and appropriate vendor API's are available
will print the document, so the the OP only adds the link once he
knows script and a window.print method are available, not after
printing.

Loads, IE, Mozilla Family, Opera and Safari perhaps being the
commonest - ie CSS can be disabled in all of them distinct from
disabling script.

Oh absolutely, it's silly (without having things like ScriptX to
provide real printing support in restricted environments) but you
can't hide scripted things via CSS, CSS and Script can be disabled
seperately in all modern browsers.

Cheers,
