Class driver for USB printers

Note: You must be root to start this driver.


devu-prn [options*] &

Runs on:



-n name
Set device name. Default is /dev/usbpar0.
-s stack
Set the USB stack name. Default is /dev/usb.
Be verbose.
-w secs
Wait up to the indicated number of seconds for /dev/stack to appear. This is useful at boot time for slow-resetting devices. Default: 60 seconds.


The devu-prn class driver manages USB printers.

Note: This manager terminates only upon receipt of a signal or on encountering a problem during startup (e.g. it can't locate the USB stack).

See devu-ohci.so or devu-uhci.so for information on USB stacks.
