View Invoices without Zooming Out

I have to zoom out to at least 80% to be able to view an invoice left-to-right all the way across (on a mac). This is very inconvenient, especially because my trackpad scroll doesn't do anything and I have to use a scroll bar on the page that sometimes doesn't appear. It would be much easier and more efficient if you could read an entire line of the invoice without zooming out or scrolling.
