Tried adding an outgoing tcp 3756 port exception to the Vista firewall but to
no avail. It still takes forever to print with firewall on (and some 5 secs
with Vista firewall OFF)

Downloaded the newest Canon LBP 5000 driver today (Jan.27.2008), R1.11 from
http://software.canon-europe.com/products/0010308.asp , removed the printer,
removed all Vista firewall printer entries, installed the newest driver and
THIS SOLVED THE PROBLEM! Now the printer prints through the Vista firewall
like a breeze.

I have been fighting with this issue for a while and finally came up
with a solution. I am not completely happy with it, because it is a
work around.
The problem seems to go away if you delete the network printer and add
it as a local printer mapped to either '\\-server-\-printer-'
(file://\\server\printer), or in my case to the IP address of the
printer.
Like I said, it works, but I would like to know why defining as a
network printer causes it to be treated differently.
