You can make changes to the appearance of a printed view (view: The combination of one or more views [Gantt Chart, Resource Sheet, and so on] and if applicable, a table and a filter. Use views to work with information in a variety of formats. There are three types of views: Charts or graphs, Sheets, and Forms.), such as the Gantt Chart view (Gantt Chart view: A predefined view that displays project tasks on the left side of the view, and graphical bars corresponding to the task's durations on the right side of the view.) or Calendar view (calendar view: A Project view that displays a project's tasks in a calendar format.), or report (report: A format in which you can print schedule information that is appropriate for the intended recipients.
