That's just a side-effect of HTTP - is wasn't designed to support
automatic upgrades to SSL/TLS from the beginning, so we need to do
a bunch of tricks to convince browsers to redirect to a https: URL
while allowing conforming clients to handle the 426 error themselves.

As for providing a https: URL for remote printers, we have no way
of knowing whether the remote end needs encryption until we try, so
the redirect is the best we can do...
