`devu-prn`

Class driver for USB printers

You must be logged in as root and start a USB stack (see io-usb) before you start this driver.

Syntax:

devu-prn [-m size] [-n name] [-s stack] [-v] [-w secs] &

Neutrino

ARM, MIPS, PPC, x86

-m size: Specify the size, in bytes, of the maximum output buffer used to write data to the USB stack. The default is 4096 bytes. Larger values may be limited by the I/O buffer limits of the USB chipset you're using.
-n name: Set the device name. The default is /dev/usbpar0.
-s stack: Set the USB stack name. The default is /dev/io-usb/io-usb.
-v: 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. The default is 60 seconds.

The devu-prn class driver manages USB printers.

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. For more information on setting up USB printers, see the Connecting Hardware and Printing chapters of the Neutrino User's Guide.

Start devu-prn with a maximum output buffer of 8192 bytes:

devu-prn -m 8192 &
