      To compile this driver into the kernel, place the following line in your
      kernel configuration file:
            device ulpt
      Alternatively, to load the driver as a module at boot time, place the
      following line in loader.conf(5):


      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 (reset) the device on the port.
      Some printers cannot handle the reset on open; in case of problems try
      the unlpt device.


      The ulpt driver provides support for USB printers and parallel printer
      conversion cables, including the following:
            ATen parallel printer adapter
            Belkin F5U002 parallel printer adapter

      The ulpt driver appeared in NetBSD 1.4.  This manual page was adopted
      from NetBSD by Tom Rhodes 〈〉 in April 2002.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
