Printing tips

In the default mode a monthly calendar is generated with day number and moon phase in the first line. Julian day and Local Mean Sidereal Time (at midnight) in the second line. Sun Rise and Set in the third line. Moon Rise and Set in fourth line. Moon Equatorial Position (R.A. and Dec.) in sixth line and if available Observer Name and Instrument in the seventh and eighth lines. In case the rise or set are not happening in that day, a **:** is appearing instead of the phenomena time. Times are in Local Time (not daylight saving time).
