There's a lot of ambiguity here. Some questions that need to be answered Is the issue that clients are unable to automatically discover these printers? Are you able to print to this printer on the GR10 if you manually setup the client PC printer config with the printers IP address? If the answer is no to both of the above. Then your focus right now should be on layer 3 roadblocks such as firewall rules, VLANs and NAT instead of Client roaming behavior and L2 mDNS/bonjour. Do you receive the same IP address when connected to the GR10 that you do when connected to the MX65W? Yes? Check switch ACL's Check MX Outbound rules, I'm not actually sure if the MX outbound rules can apply to traffic bridged between wired/wireless in a similar fashion to the MR L3 rules. You can throw in an Allow Any Any at the top of the MX outbound rule set and see if behavior changes. ) No? Is the GR10 SSID clients are connecting to configured with Guest Mode enabled? Yes? Disable Guest Mode (or throw in an exception for the printer IP if one's configured) Are VLAN's configured? Yes? Check MX outbound firewall rules. Last rule is allow any any. If you have any custom L3 rules throw in allow any any above them to see if that resolves the issue.
