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



           NAME
                lp - line printer

           SYNOPSIS
                device lp vector lpintr

           DESCRIPTION
                _▶08◀L_▶08◀p 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  char-
                acters are escaped according to the following table:

                {         -▶08◀(
                }         -▶08◀)
                `         -▶08◀'
                |         -▶08◀!
                ~         -▶08◀^

                The driver correctly interprets  carriage  returns,  back-
                spaces, tabs, and form feeds.  Lines longer than 132 char-
                acters are truncated (This is a parameter in the driver).
