USB hubs on routers, such as an Apple AirPort or Time Capsule, are not
the same as a USB port on a computer or device. These USB ports are not
supported for printing with the Leitz Icon printer. We recommend connecting
directly to a USB port on a computer for printing on the Leitz Icon
printer, or setting up the printer for wireless printing as described in
the Quick Start Guide or How To Connect Articles available here.
