LP(4)                   GENIX Programmer's Manual                   LP(4)



      NAME
           lp - line printer

      SYNOPSIS
           device lp vector lpintr

      DESCRIPTION
           Lp provides the interface to any  of  the  standard  Centronix  line
           printers.   When  it  is opened or closed, a suitable number of page
           ejects is generated.  Bytes written are printed.

           The unit number of the printer is  specified  by  the  minor  device
           after  removing  the low 3 bits, which act as per-device parameters.
           Currently only the lowest of the low three bits is  interpreted:  if
           it  is  set,  the  device  is  treated as having a 64-character set,
           rather than a full 96-character set.  In  the  resulting  half-ASCII
           mode,  lower  case  letters  are  turned into upper case and certain
           characters are escaped according to the following table:

           {         (
-
           }         )
-
           `         '
-
           |         !
-
           ~         -
^

           The driver correctly interprets carriage returns, backspaces,  tabs,
           and  form  feeds.   Lines  longer  than 132 characters are truncated
           (This is a parameter in the driver).
