/lib/firmware/hp/sihpP1005.dl - google for it

/etc/config/p910nd

config p910nd
        option device        /dev/usb/lp0
        option port          0
        option bidirectional 0
        option enabled       1

/dev/usb/lp0 shoud be present
first try cat /lib/firmware/hp/sihpP1005.dl > /dev/usb/lp0
printer flashes red light and rotates mechanics

then test unplugging and plugging, power off/on
check /var/log/hp
