ULPT(4)		       FreeBSD Kernel Interfaces Manual		       ULPT(4)

NAME
     ulpt -- USB printer support

SYNOPSIS
     ulpt*   at	uhub?

DESCRIPTION
     The ulpt driver provides support for USB printers that follow the printer
     bi- or uni-directional protocol.  The bits	in the minor number select
     various features of the driver.

	   Minor Bit	Function
	   64		Do not initialize the device on	the port.

FILES
     /dev/ulpt?

     For some HP LaserJet printer models (1000,	1005, 1018, 1020), the driver
     needs at least version 1.0	of the following firmware files, which are
     loaded when a printer is attached:

	   /etc/firmware/ulpt-hp1000
	   /etc/firmware/ulpt-hp1005
	   /etc/firmware/ulpt-hp1018
	   /etc/firmware/ulpt-hp1020

     These firmware files are not free because HP refuses to grant distribu-
     tion rights.  As a	result,	even though OpenBSD includes the driver, the
     firmware files cannot be included and users have to download these	files
     on	their own.  A port which can download and install the firmware can be
     found in /usr/ports/sysutils/firmware/ulpt.

HISTORY
     The ulpt driver appeared in NetBSD	1.4.  OpenBSD support was added	in
     OpenBSD 2.7.
