Firewall interference

Hello Bob. Sorry to hear about that. Please have a look at this article http://avgread.me/1FaBjq7 . Thank you.

Approximately 10 days ago I began having problems with the wireless connection between my computer and my HP Photosmart 7520 printer.  When I checked the network the connection it showed to be good.  When I tried to reinstall the printer the diagnostic showed 3 possible problems with the first being inference with the firewall.  I momentarily disabled the firewall and was able to print.  I again enabled the firewall and the printer does not connect and am using an older USB connected printer.  How do I have both the firewall and printer functioning?
