The Sequence Diagram Editor has a Pagination Preview mode which shows the subdivision of the sequence diagram into multiple printed pages and also allows you to set the print page orientation and page overlap.
In a sequence diagram, the Pagination Preview mode is controlled from View > Pagination Preview.
In the main display, you can set the Pagination Preview mode as well as set page orientation and page overlap by the following preferences, accessed from the Project > Preferences Management>Sequence Diagram Graphic Editor:
● Pagination Preview (Yes/No) - Enables Pagination Preview mode
● Pagination Orientation (Portrait/Landscape) - Defines the page orientation to be used in sequence diagram pagination
● Pagination Overlap Ratio ([%]) - Defines the desired overlapping area, which will be printed twiceNote: These preferences also affect the Documentor. In order for changes in Preferences values to take effect in the Documentor, the Documentor should be closed and re-opened.
