Formatting issue – gray spots showing up

Hi,

I have installed print-o-matic and am happy with it, but I am seeing some gray spots or upright ovals around the printer button and text. it is showing in firefox, IE and chrome.

I am assuming the print code or styling is interfering with some other styles from the site? I am not knowledgeable enough to figure this out though!

Can anyone help?

Thanks!
