Here is the minimum kernel :

__kernel void PRINT_SIZEOFs  (void)
{
        printf("size_of_short                      : %u\n", sizeof(short));
        printf("size_of_int                        : %u\n", sizeof(int));
        printf("size_of_long                       : %u\n", sizeof(long));
        printf("size_of_float                      : %u\n", sizeof(float));
}

And the output :

If you are talking about computer programming in using PRINTF function. Found this website with very detail explanations using PRINTF.: Tearing apart printf() – MaiZure's Projects 

Otherwise, not sure what you are asking.

EDIT: If this concerns Opencl programming maybe you should ask at AMD OpenCL Forum: OpenCL‌
