     ulpt - USB printer support

     To compile this driver into the kernel, place the following line in your
     kernel configuration file:

     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.

     conversion cables, including the following:

        ATen parallel printer adapter
