Hi,
I installed an Epson TM-T20 II without problem using the armbian image for z28 tvbox, rockchip rock64 alike board. When I plug it, it creates a /dev/usb/lp0 port that is enough to make the printer work.
But I am unable to get the same working on the amlogic images. No port is created when I add the USB printer. Could it be missing UDEV rules? Or usblp driver not being loaded by the kernel?
May someone give me a light? Those boxes are optimal for POS installations, and no support for ticket printing is a handicap.
BTW, awesome work with all this project, it helped me a lot.
