Printing really small!

I recently updated my site, prior to which all was working well except for the small logo issue which was partly the reason to update. However not only is the logo small, but the whole thing is now reduced, by about 50%.

I’ve check my printer settings and they haven’t changed, the only thing I have done is to update wordpress and the plugin.

Any ideas?
