I didn't think I was Using secure Printing? I just received the same
error as in Ryan Sinnwell's post on 11/29/05.
We had been using NIPP412 for some time and then when I tried adding XP
drivers for a HP Laserjer 2200DN I got that error:
"The SSL connection has been closed".

Does the 412 client autmatically use Secure Printing?
I followed the suggested fix and installed the Nile Beta. I haven't
rebooted server yet though.
