How about this (appologies for source in this newsgroup... It's short)

#include <stdio.h>
#include <stdarg.h>

void gprintf(int x, int y, char *fmt, ...)
{
    va_list params;
    char    str[80];

    va_start(params,fmt);
    vsprintf(str,fmt,params);
    va_end(params);

    outtextxy(x,y,(char far *) str);
}

I may have left off a graphics library header here.  This is untested.
Don't forget to prototype it where used.
void gprintf(int x, int y, char *fmt, ...);
usage:  gprintf(1, 1, "Hi mom, i=%d", i);

No warranties, I speak only for myself, ...
(varargs disclaimer :-)               ^^^^^
