I bought this printer for work for a device that uses Pictbridge out of a mini-USB jack.I have the device connected to the printer with mini-USB-->USB-B cable. The TS6420 has the Pictbridge settings in the menu enabled but the upstream device can't find it. I notice that the 6420 manual repeatedly mentions 'wifi Pictbridge" but suspiciously avoids mentioning Pictbridge over USB.
Has Canon changed the rules and disabled Pictbridge over USB? The Pictbridge format has been around since 2003. Why would Canon release a printer that doesn't adhere to the 2 decade standard?
