My network printer stoped working with AVG Business edition

Hello Niven,
We regret for the inconvenience caused. Please follow the instructions to change the Firewall settings to check if that works: Open AVG Zen -> Internet Security -> Click on Menu in the top right corner -> Settings -> Components -> Firewall -> Customize -> Network Profiles -> Change the networks from Public to Private (If it is in Private, change it to Public).
If the issue persist,get connect to us we are here to help you.
Thank you.

Niven, If that doesn't help… Business products support… For assistance have a look @ this AVG webpage (https://support.avg.com/business_contact_form?l=en_US). Please be informed that this Community forum basically deals with 'home' version of AVG products.

The Printer shows port in use when trying to print. When I disable AVG the printer works.

Please Help!!
