.SH NAME
-\fBmcprint\fR - ship binary data to printer
+\fBmcprint\fR \- ship binary data to printer
.SH SYNOPSIS
\fB#include <curses.h>\fR
-
+.sp
\fBint mcprint(char *data, int len);\fR
.SH DESCRIPTION
This function uses the \fBmc5p\fR or \fBmc4\fR and \fBmc5\fR capabilities,
if they are present, to ship given data to a printer attached to the terminal.
-
+.PP
Note that the \fBmcprint\fR code has no way to do flow control with the printer
-or to know how much buffering it has. Your application is responsible for
+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
+(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.
-
+.
.SH RETURN VALUE
-The \fBmcprint\fR function returns \fBERR\fR if the write operation aborted
-for some reason. In this case, errno will contain either an error associated
-with \fBwrite(2)\fR or one of the following:

-Capabilities for printer redirection don't exist.
+Capabilities for printer redirection do not exist.
.TP 5
ENOMEM
Couldn't allocate sufficient memory to buffer the printer write.
-
+.PP
When \fBmcprint\fR succeeds, it returns the number of characters actually
sent to the printer.
.SH PORTABILITY
Padding in the \fBmc5p\fR, \fBmc4\fR and \fBmc5\fR capabilities will not be
interpreted.
