          NAME
               slp - SunRiver parallel printer interface

          DESCRIPTION
               The slp driver is part of the INTERACTIVE UNIX System Sun-
               River Fiber Optic Station support facility.  It provides the
               support for connecting a line printer to the back of the
               SunRiver Cygna 386 Station.  The close waits until all out-
               put is competed before returning to the user.  The lp driver
               allows only one process at a time to write to the printer.
               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.
