Could it supports to send "GET_DEVICE_ID" to get the usb printer info, like the "usb_printerid" cmd
Your lib is great, works on esp32s3!!!
Could it supports to send "GET_DEVICE_ID" to get the usb printer info, like the "usb_printerid" cmd.
To follow the spec: https://www.usb.org/sites/default/files/usbprint11a021811.pdf , and use linux cmd usb_printerid, we can easy get the usb printer DEVICE_ID info:
sudo usb_printerid /dev/usb/lp2
GET_DEVICE_ID string:
MANUFACTURER:Gprinter ;COMMAND SET:TSC;MODEL:GP-3120TUC;CLASS:PRINTER;PROTOCOLS:IEEE1284.4;OPTIONS:INTPSRVR
Does it possible?
here is the usb traffic related to the GET_DEVICE_ID
