mcprint - ship binary data to printer
int mcprint(char *data, int len);
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.
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

When mcprint succeeds, it returns the number of characters
actually sent to the printer.
The mcprint call was designed for ncurses(3x), and is not
found in SVr4 curses, 4.4BSD curses, or any other previous
version of curses.
