Bonjour found and added my Printer... but only Pretends to Print.

Windows 7; Cannon Printer USB Connected to a 2010 Model Airport Express (Firmware has been upgraded)

--Bonjour did as advertised. It helped me discover and add the right print driver to my Printer list in Windows 7.

--Then the PC does a great job of pretending to print. The driver comes up as normal; the dialogue boxes are right.

--Then it even queus the document for printing.

--Then NOTHING happens. It all stops and dissapears.

Firewall? I read in an archived post that firewals may be causing this.

So, I turned off the firewall. It didn't work.

VPN? I read somewhere that it's possble a VPN can interfere with the Port.

So, I turned that off too. It still didn't work.

I hope someone can help.

Thanks!
