[Printing-architecture] Ubuntu Natty the first distribution which does automatic download of binary printer driver packages

[Olaf Meeuwissen]

Hi Till,

Saito-san and I have been looking at how well the automatic download
works when behind a proxy.  Short story: it doesn't.  The long story
follows below.

We upgraded Natty on 2011-03-03 and applied your patch to
system-config-printer.

That's what we did.  We've been looking at jockey debug logs, wireshark
network traffic captures and the jockey code trying to figure out where
things went wrong.  According to the logs, the query of the OpenPrinting
DB went just fine.  It's getting the fingerprint that bombs.  Using wget
to fetch the fingerprint in the same environment works fine.
