Bitdefender Total Security 2018 blocking printer

I just had to fix this on my computer this morning. This rule assumes all traffic to/from the printer IP address can be trusted. I'm going to work to narrow this down, but this should work.

In Bitdefender select {B} icon, View Features, Firewall {settings/gear} icon, Add rule:

   Settings tab:

      Apply this rule to all applications: YES

      Permission: ALLOW

      Network Type: ANY NETWORK  (Home/Office would be more secure if that works)

      Protocol: ANY (TCP might work and would be more secure if that works)

      Direction: BOTH

   Advanced tab:

      Custom remote address: ON

      IP: (enter the IP address of your printer e.g. 192.168.1.2)

      Ports: (leave blank if you are not sure)

   Click OK

Odd - that rule allows all traffic to/from the printer ip address, and worked for me on a Brother laser printer.

Did you try rebooting your computer after creating the rule? It might be possible the print spooler or a printer specific application was hung from an earlier printing attempt before you created the rule.

Does printing work if you turn the firewall completely off? Did printing work before you installed Bitdefender?

I'm just a user, but these are the steps I would take to troubleshoot this.

In TS 2018, go to Main screen > Protection - View Features > Firewall Settings (the little gear in the bottom of the Firewall box) > Rules > Add Rule .   Select Apply this rule to all applications = Yes.  The click on Advanced > Custom Remote Address = Yes.  Enter the IP address for your printer there.  Leave the port number blank for now.  Click OK.  You may have to reboot your system after adding this rule but you should now be able to print directly to your Local Printer.
