USB printers

I attempt to start USB printer HP LaserJet 1020:

io-usb &
mount -T io-usb /dev/io-usb/io-usb
mount -T io-usb /dev/io-usb/io-usb
mount -T io-usb /dev/io-usb/io-usb
waitfor /dev/io-usb/io-usb
devu-prn &

But it doesn’t work. The device such as /dev/usbpar0 doesn’t appear.

command usb print such information

  • Configuration : 1

Maybe I incorrect run driver of usb printers or this model of printers isn’t supports?

This model of printer using host-printing system of printing and QNX doesn’t support it.

:exclamation: It is correct way to run USB printer.

[size=150]io-usb -duhci
waitfor /de/io-usb/io-usb
spooler -d /dev/usbpar0
If I use HP Laser Jet 1160 it is working correctly.
