Have you checked out Keil's User Guide:

Cx51 User's Guide - printf()

A couple of good tutorials:

C Tutorial – printf, Format Specifiers, Format Conversions and Formatted Output

Secrets of “printf”

The Keil compiler sends printf() output to STDOUT, which I believe is UART1. So if you need to define STDOUT as another UART or other peripheral, you need to modify some code and recompile, check Keil's website for details.

Here's a Keil Forum discussion on printf():

UART - printf - keil

These links and docs should get you started in the right direction.
