    "DO i have to use it in the serial ISR or in the main code ??"

    Absolutely do not use printf in any ISR!

    You just use printf as you would in any 'C' program; eg, the classic "Hello, world!"
    printf ends up using putchar - C51 provides a standard, non-interrupt-driven implementation which uses the standard 8051 UART. You may need to customise it to your own requirements; eg, different port, interrupt-driven, etc

    This is documented in the manual, there's an example in the downloads section, and Mark has given you his own implementation!
