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] &

Runs on:

Neutrino

Targets:

ARM, MIPS, PPC, x86

Options:

-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/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.

Description:

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.

Examples:

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

devu-prn -m 8192 &
