Compile with:

cc sethp.c -o sethp

#include <stdio.h>

/* turn on word wrap and select */
/* Courier 12 cpi 10 pt. font */
#define INITSTR \
"\033&s0C\033(0N\033(s0p12.00h10.0v0s0b3T"

fputs(RESETSTR, stdout);        /* reset printer */

fputs(INITSTR, stdout); /* send setup string */

/* send data straight through */
while ((c = getchar()) != EOF)
putchar(c);

/* send form feed at end of job */
fputc('\014',stdout);
fflush(stdout);
