How can I print breaks between lessons?

Once you add a break - =Cómo puedo especificar Recreos largos/ Recreos de la comida -
you can use specific settings for printouts.

In menu: School - Bell times/Rename periods - select the break - Edit open the dialog with Break's details.

Then you can specify:
- Text for printouts - a custom text that will be printed in the printouts:

- In Printouts area you can select the reports in which this break should be printed.
You can select all summary reports and/or individual reports for teachers, classes, classrooms.

- by selecting specific Bell you can print the break only in classes timetables, which are assigned to selected Bell. Be careful, this is common mistake that you use this settings incorrectly. Please, see this: Why some of the periods are not displayed in print preview?
