Do not connect canon mf4820d plz help
Here is the list of printers supported by PrintHand app:
Also here is the list of supported portable printers:
Make sure that your printer is supported.
If the printer cannot be detected by the app, please try to:
* power-cycle the printer (we would advise switching it off and then waiting for about a minute before turning it back on);
* reboot the computer (if the printer is connected to it);
* reboot your mobile device.
If that does not help, you can try to:
* reinstall the app;
* un-share the printer from your network and then share it again using standard tools of the OS.
Please note that you have to configure your printer if it supports wireless connectivity using the network utility tool that came with it (probably on an installation disk). If a wireless printer is not shared through the router using this piece of proprietary software provided by a printer manufacturer, no devices (including your mobile device) are going to detect your printer.
Both your mobile device and your printer should be connected to the same wireless network.
Have a nice day,
