Some operating systems (such as UNIX or Windows in enhanced mode) use virtual memory. Virtual memory is a technique for making a machine behave as if it had more memory than it really has, by using disk space to simulate RAM (random-access memory). In the 80386 and higher Intel CPU chips, and in most other modern microprocessors (such as the Motorola 68030, Sparc, and Power PC), exists a piece of...

I think the original question was not a typo. The original question was printf, not fprintf, compared to cprintf. And I think printf output goes to stdout (standard out) which by default goes to con (the console). cprintf output goes only to con.
