Network printer cannot scan file to pc

Question

I have an XG 115 with an AP 100 and passive switch connected 
 The network printers are connected to the switch and the switch to the on port 1 Lan 
 The network printers have a static IP 
 The network printers are printing over the network 
 The firewall rules are Wireless to Wan, Wireless to Lan, Lan to Wireless, Lan to Lan, Lan to Wan and Default Network Policy 
 When I press "Scan' on the brother MFC 7632N network printer, it displays on the Led "Check Connection" 
 (The Scan option was working, allowing Scan to network PC/Laptop before installing XG, AP100 and switch 
 This message "Check Connection" is the result of not being able to find other network devices i.e pc/laptop on the network 
 This indicates that either the switch is not routing the scan connect request or I need a firewall rule 
 
 Thanks for your help

Nigel, 
 if printer and computers are on the same network, firewall rules are not needed (firewall rules are needed only when you need to traverse from one network to another). 
 If your AP is bridged to LAN, no firewall rules are needed (as I described previously).

HI Nigel 
 As you are using AP and if the traffic is traversing through the XG then you may need rules to communicate with the network on another zone. I am assuming you are using as a Gateway mode and so the Broadcast packets that is used to discover the system in your network may not pass through XG as it would drop broadcast packets as per standard. 
 If you network are bridged via interfaces and if you are using Sophos AP , then you may need to disable Client Isolation on your AP settings on XG. Other AP may have client isolation on the device itself and is applicable for Multiple Network on the same AP . If you are using different AP , check if there are traversing through a L2 switch or not.
