It prints just fine for me...
But then again, I opened it in KGhostview, in Linux. Acrobat isn't the
only software that can read a PDF. And, I doubt the other
buttons/commands could disable the buttons in KGhostview.
On the other hand, going to one of the ebook formats, either Microsoft
Reader, or the Adobe one, may give you some other protection, in that
they'll be unreadable (and useless) unless you use the only supported
software.

Nope...
HTTPS just encrypts the connection. Your browser still caches a local
copy to render the page. Depending on your browser & settings, this
local copy may get deleted when you close it, but at least while it's
open, it's on your hard drive.

Interesting. I see the same results using Konqueror. I grabbed the page
using wget, but it was one big long encrypted string wrapped in a java
script tag. I could, however, easily print it and select text.
