Amit Daniel Kachhape6a01f52011-07-20 11:45:59 +0530[diff] [blame]62 This function uses the <STRONG>mc5p</STRONG> or <STRONG>mc4</STRONG> and <STRONG>mc5</STRONG> capabilities,
63 if they are present, to ship given data to a printer
64 attached to the terminal.
65
66 Note that the <STRONG>mcprint</STRONG> code has no way to do flow control
67 with the printer or to know how much buffering it has.
68 Your application is responsible for keeping the rate of
69 writes to the printer below its continuous throughput rate
70 (typically about half of its nominal cps rating). Dot-
71 matrix printers and 6-page-per-minute lasers can typically
72 handle 80cps, so a good conservative rule of thumb is to
Steve Kondikae271bc2015-11-15 02:50:53 +0100[diff] [blame]73 sleep for a second after shipping each 80-character line.

Steve Kondikae271bc2015-11-15 02:50:53 +0100[diff] [blame]80 either an error associated with <STRONG>write(2)</STRONG> or one of the
