       NAME
             lp - parallel port interface

       DESCRIPTION
             The parallel port (lp) driver supports both the primary
             (monochrome) and secondary parallel printer adapters
             simultaneously.  Up to two printers are supported.  If an
             adapter for a printer is not installed, an attempt to open it
             will fail.  The close waits until all output is completed
             before returning to the user.  The lp driver allows only one
             process at a time to write to the adapter.  If it is already
             busy, an open for writing will return an error.  However, the
             driver allows multiple opens to occur if they are read-only.

             The parallel printer adapters are character devices.  The
             minor device number corresponds to the primary or secondary
             parallel printer adapter.  Thus, minor device 0 corresponds to
             the primary parallel printer adapter, while minor device 1
             corresponds to the secondary adapter.

             The parallel port behaves as described in termio(7).
