How to rescan usb printer from Astroprint dashboard site?

Hi, I connected via USB my Printer Wanhao i3 to my RPI - Astrobox and a Logitech camera, the astrobox is always on, but the printer no. I can turn on the printer remotely through a websocket relay 220v, but unfortunately by the Astroprint site I can not do rescan of USB to show the printer to astrobox , how do I fix?
Thank you in advance

@Giorgio: You cannot do a USB Re-Scan of your printer via the AstroPrint Cloud.

You’ll need physical access to the box – or setup remote access to the box itself using port forwarding etc (which is NOT recommended for obvious security reasons)

It’s an interesting situation though.

I leave my printer on 24/7, so haven’t run into this problem…

Yes, It would be nice if it were implemented in astroprint cloud.
Thanks again for your quick answer.
Giorgio
