can not get printing

[clstephan at wanadoo.fr]

hi!

I try to install a HP printer connected to USB.

Following HP recommendation, I have to select a device when I reached
http://localhost:631/admin

unfortunatly, what ever is the USB port selected I get

unable to open USB device "usb:/dev/usb/lp0 (up to 15 according to the selected port)" : no such device

device URI:usb:/dev/usb/lp0

sorry for that question which look so basic
