+ 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.
