Dear
few months ago I recovered an HP P4515N LASER PRINTER that works really fine via USB cable to my HP computer.
I bought a SAMSUNG GALAXY NOTE 10.1 2014 and I tried to print via USB+OTG cable directly to HP P4515N. Unfortunately the named printer is connected but when I push "print" the printer looks like to be not connected. the USB CARD of the printer looks to be not compatible. I connected the same NOTE 10.1 2014 using the same USB Cables to my new HP 1010 printer and it works really fine. So, since it is not a SAMSUNG problem, could you please try to help me telling me how to configure p4515n USB Port in order to let me print using note 10.1 via usb. Pls I haven't any wireless or other way to connect the printer either then the USB CABLE. the printer is updated at the latest firmware available on your hp site.
So, I wait for your kind support,
Ciao
Giuseppe
