int mcprint(char *data, int len);
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.
When mcprint succeeds, it returns the number of characters actually sent to the printer.
