import rospy
import roslib
import tf
import sys

import serial, string, math, time, calendar

if __name__ == '__main__':
    rospy.init_node('Compass', anonymous=True) 

    try:
        while not rospy.is_shutdown():
            rospy.logwarn("Angulo yaw: %.1f", z_axis_direction * orientation_rad / math.pi * 180.)
            print " Print "
            sys.stdout.write("stdout")
                rospy.loginfo("ros info")
    pass

Rospy log warn prints in a console but like a warning message with yellow color. Print and stdout not do anything. And finally rospy log info print in a /rosout topic.

Edit 1: The launch

<!-- Compass nodo of Furuno PG-1000 -->
<launch>
       <node name="compass1" pkg="nodos_creados" type="FurunoCompassNode.py" respawn="true">
       </node>
</launch>
