You must tell the compiler that the printf() function is not the one of your class but from global name space:

C++

void CPrint::printf()
{
  ::printf("Test");
}

In general it is a bad idea to use names of standard library functions as member function names. With C++ classes, it is common to let member function names begin with an uppercase letter:

C++

class CPrint
{
  void Printf();
};

// Source File

void CPrint::Printf()
{
  printf("Test");
}
