AVG Firewall blocks multifunction printer

by perrydw / January 7, 2010 2:38 AM PST

AVG 9 blocks the scanner function on my multifunction printer. I have "safed" the file sharing and printer functions but that doesn't work. Turning off AVG firewall solves the problem. I'm now using the Windows firewall but would rather use the AVG one. How do I solve this problem?

AVG Firewall is part of paid AVG.
To solve firewall issues, most of the time diagnostic files are needed to analyze the situation.

Please proceed as follows:
1. Download this diagnosis tool:

Induce the issue multiple times(attempt to scan)

Run the diagnostic tool downloaded in step 1. and continue as per displayed readme.

FIrewall blocks printer

It would appear I too have the same issue...and sadly i have tried multiple times to get HP or AVG to work together. Apparently this issue has gone on for a long time. I have done the diagnostic thing....i have paid for this AVG for another two years. If I had known that this would be an ignored issue I would have not bothered to renew. I cannot afford to waste the time needed to manually configure the firewall to connect to a $450 printer that works flawless with my firewall disabled. I do not understand how and why a rule cannot be created for HP products , such as printers, that allows traffic on a network IP i assigned as safe. Maybe AVG will lose another customer {approx 5 yrs x 5 licenses each yr} this will be the 2nd or 3rd year with no answer to this issue. And to think I actually got 20 some odd people to switch to them from Norton!

We apologize for the inconvenience.

Unfortunately some scanners and printers are communicating over the network using special ports.
It is not possible to create general rule as IP adresses and ports used may wary from user to user and analysis of the communication is needed so we can provide with advice how to set up your firewall properly.

If you still experience the issues please contact our support as described above.

Thank you.

I understand what you are saying. Will I need to setup printer with the firewall off, and then enable firewall afterward to get the traffic logs necessary? The new setup utility i have from HP cannot find the printer on my network if the firewall is on. I can add the printer in windows and just print with it with the firewall on now. I would like to use all the functions of this printer as i bought it for these reasons. I have multiple versions of AVG w/firewall running on different machines. 1 has win 7...one with vista...and the others with XP home and pro. I guess I misunderstood why the utility designed to add the printer and establish the proper communications is not allowed to do so by a firewall that normally prompts the user on these actions and allows us to approve or deny these communications. I have added my home network IP range as "trusted" and tried to allow communications on ports 9220, 161, and 427....just to name a few ports that my printer needs.

it is needed to gather AVG logs after inducing the connection issue (HP printer cannot connect) so the information will be recorded in the AVG firewall log.

Else for HP printers is suggested (if they are using the same static IP address) to add the IP addresses to AVG Firewall Whitelist. Please note that this will allow all incoming and outgoing communication to the whitelisted IP address. Make sure that you only allow the address of the HP printer or that this address is not used by another device you do not want to allow in future (e.g. after moving the computer to another network).

1. Open the AVG Program.
2. On the Tools menu, click "Firewall settings."
3. In the left tree menu, expand the Profiles item, and then select your firewall profile (for example "Computer in domain" or "Small home or office network"), and then click "Defined networks."
4. Locate "IP addresses whitelist" in the list of networks and double-click it.
5. Click Add IP.
6. Type the necessary values defining your local network (the IP address of your HP printer).
7. Confirm all changes by clicking OK (in all open dialogs, including the "Firewall settings").
8. Test the connection between your computer and the printer.

Thank you

wireless printing w/AVG and HP

OMG--pretty simple fix but took me forever to find this link. It was a bit confusing as the IP address was already allowed. However I followed your instructions and can now print wirelessly! Thanks!

Unable to print with HP7200 series through AVG firewall

Lifesaver. After all the trouble and hours of AVG firewall configuration, finally a very simple fix. Kudos...

Finally got it to work!!!! My computer FINALLY will read my HP Officejet 8500:

Open AVG Interface
Click Firewall Settings
Under "PROFILES": CLICK "Defined Networks"
On the right panel: Click "ADD NETWORK"
Networks Property window will open
Network Name: HP Devices
Network Description: TYPE:The list of IP addresses that are always allowed for both incoming and outgoing traffic regardless any other rules.
Click "ADD"
ONE IP ADDRESS: Type in your printer's IP Address
Click: OK

As you close out your AVG window you should get a notice that AVG is reconfiguring to notice the printer.

I hope this works for you. It is hard to go back and retrace your steps. This was trial and error.

Good Luck!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
