AirPrint: Printer Duplicated on iOS Device

How to Resolve Duplicate AirPrint Printers on Your iOS Device Effortlessly

Issue:

On the iOS device, one device shows twice when browsing AirPrint to select a printer.

Reason: the same name has been given to Mobile Print Setting -> Printer name, which is a 'virtual' print queue for mobile printing, as an existing device.

Resolution:

Change the name in Mobile Print Settings -> Printer name and restart the EveryonePrint Mobile Gateway service.

Note: the "-" sign is stripped out when publishing the AirPrint device, so Printer-A becomes PrinterA.
