Qbasic writes directly to video memory, I believe.  printf() uses stdout, which I assume uses the low-level DOS call to send a string of characters to the console.  I don't know of a solution using the std C functions, but maybe allegro's textout() might help.  You might also try writing a function that uses a BIOS interrupt and redirecting that... but I don't think redirection picks it up at the DOS level.
