I actually sometimes order filament from another supplier due to this. It's be really great if either the order information page or the order confirmation email had a PDF copy or print friendly copy of the invoice. The email comes out with loads of junk on it (including the massive logo) and our accounts team don't really like accepting emails. I have to submit expenses electronically as a PDF so the only option is to open the orders page and print to PDF, it's all a bit clumsy and even that view isn't really print friendly.
