+ This function uses the mc5p or mc4 and mc5 capabilities, if they are
+ present, to ship given data to a printer attached to the terminal.
- Note that the mcprint 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 typically
- handle 80cps, so a good conservative rule of thumb is to
- sleep for a second after shipping each 80-character line.

RETURN VALUE
- The mcprint function returns ERR if the write operation
- aborted for some reason. In this case, errno will contain
- either an error associated with write(2) or one of the
- following:

Capabilities for printer redirection do not exist.

- Couldn't allocate sufficient memory to buffer the

- When mcprint succeeds, it returns the number of characters

PORTABILITY
- The mcprint call was designed for ncurses(3x), and is not
- found in SVr4 curses, 4.4BSD curses, or any other previous
