Summary
Use this tab page to enter or edit user data. User data is used by templates and Wizards in LibreOffice. For example, the "First name" and "Last name" data fields are used to automatically insert your name as the author of a new document. Some of the user data is included automatically in an internal dictionary so that it is recognized by the spellchecker.

Printer Warnings
Defines which warnings appear before printing begins.

High Contrast Appearance
High contrast is an operating system setting that changes the system color scheme to improve readability. You can decide how LibreOffice uses the high contrast settings of the operating system. Cell borders and shadows are always shown in text color when high contrast mode is active. The cell background color is ignored then.
