I struggled a bit when the form was completed because I failed to see where the "Print" button was located, but a rep from Customer Care (Paul) helped me and I was all set. Looking forward to exploring and using the PDF filler site frequently.

Great for my online classes! This has been a great tool for editing PDFs for my Anatomy class. The only problem is the "drawing" tool does not provide enough color options. It's very limited.
