On the pop out window Type a friendly name for the printer group on the Name field, Select the printer objects you created on the previous step and add them to the group clicking on the right pointing arrow middle button and Click “ok” to create the network printer group
Next, lets create the access rules in the SonicWall device that will enable printing from wifi devices to the local area network wired printers
Click on Rules and then “Access rules” on the left menu
Click on the “Add” button at the top to create the new SonicWall access rule
Select “allow” on the Action, in the field “From”,
Select WLAN on the “From” field to indicate that traffic will be originated on the wireless network
Select LAN on the “To” field to indicate that traffic will be open to reach the wired network
Select any on the “Service” field
Select “WLAN Subnets” on the “Source” field
Select Destination the name of the wired printer group created on the previous step, in my case “LAN-Printers”
Click on “Add” to complete adding the SonicWall access rule.
You could have selected “Any” on the “Destination” field, however that will open your entire wired LAN to any virus or crypto viruses your mobile devices might be infected with. I highly advise you not to do that, since it will make your entire wired local area network more vulnerable to this type of events.
