Airprint printers showing printers are offline after the first successful print job - c06358114
This issue is usually due to not using IPP port 631 over the SSL.
Ensure PDG (Print Delivery Gateway) is set to listen on port 631 and SSL enabled.
This can be found found here: PrinterOn Configuration Manager > Advanced > Components > Print Deliver Gateway > Configure > Networking > Default IPP port
After changing the port configuration, the PDG service needs to be restarted.
In order to see the above setting, you might need to enable the Advanced View in PrinterOn Configuration Manager.
