Version 2018.00 improves the right-click "Quick Print" command to work with multiple selected items. In the previous version, the Quick Print command wouldn't do anything when multiple items were selected.
To select multiple items (events, tasks, notes, or contacts) for printing, click each item while holding the Ctrl key. A range of items can be selected by clicking the first item and holding the Shift key while clicking the last item. All items between the first and last clicked item will be selected. This method of selecting multiple items works on both the calendar view (Day, Week, Month tabs) and the list views. Selected items are indicated with a thick black border.
After selecting the items you'd like to print, right-click any of the selected items and then click the "Quick Print" command. You can also press the Ctrl+Shift+P keyboard shortcut.
The selected items and their details will be printed in an "agenda" format, as shown in the example below.
