NAME
       mmccpprriinntt - ship binary data to printer

SYNOPSIS
       ##iinncclluuddee <>

       iinntt mmccpprriinntt((cchhaarr **ddaattaa,, iinntt lleenn));;

DESCRIPTION
       This  function  uses  the mmcc55pp or mmcc44 and mmcc55 capabilities, if they are
       present, to ship given data to a printer attached to the terminal.

       Note that the mmccpprriinntt code has no way  to  do  flow  control  with  the
       printer  or  to  know  how  much buffering it has.  Your application is
       responsible for keeping the rate of writes to  the  printer  below  its
       continuous  throughput  rate  (typically  about half of its nominal cps
       rating).  Dot-matrix printers and 6-page-per-minute  lasers  can  typi-
       cally  handle  80cps,  so a good conservative rule of thumb is to sleep
       for a second after shipping each 80-character line.


RREETTUURRNN VVAALLUUEE
       The mmccpprriinntt function returns EERRRR if the  write  operation  aborted  for
       some  reason.  In this case, errno will contain either an error associ-
       ated with wwrriittee((22)) or one of the following:

       ENODEV
            Capabilities for printer redirection do not exist.

       ENOMEM
            Couldn't allocate sufficient memory to buffer the printer write.

            When mmccpprriinntt succeeds, it returns the number of  characters  actu-
            ally sent to the printer.

PPOORRTTAABBIILLIITTYY
       The mmccpprriinntt call was designed for nnccuurrsseess(3X), and is not found in SVr4
       curses, 4.4BSD curses, or any other previous version of curses.

BUGS
       Padding in the mmcc55pp, mmcc44 and mmcc55 capabilities will not be  interpreted.
