Cool, though I'm almost disappointed now. I was hoping you had figured out some hack to use the browser's 'print to file' functionality, omitting the sidebar and printing only the invoice part of the web page.

that can be done with a print-only stylesheet. display: none for the sidebar

If you give would like to discuss this on Product Hunt, you can give me your twitter handle and I can give you access there as it's on the home page. Nice job btw

I'd love to, thanks. My Twitter handle is the same as my username on here. :)

sent!
