Not sure if this will do what you want, it's a port from Themies XLib.

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

void my_printf(int x, int y, BITMAP * bmp, int color, char *ln,...)
{
  char dlin[100],*dl=dlin;
  va_list ap;
  va_start(ap,ln);
  vsprintf(dlin,ln,ap);
  va_end(ap);
show_mouse(NULL);
  textout(bmp, font, dl, x,y,color);
show_mouse(screen);
}
