The image selection to print must be prepared before calling the print function. If you need to print more than one image per page, choose a layout from the dropdown button in the toolbar (1).
The layout list is built dynamically according to the window size. So changing the window size ratio will provide other layouts. For instance, with a panoramic screen, you can choose a horizontal layout and then print with a landscape orientation.
To fill the layout with images you can change the synchronized mode of series (2):
From the main menu, open File > Print > Print 2D viewer layout (P).
The meaning of the standard print parameters:
From the main menu, open File > Print > DICOM Print.

The DICOM printer configurations can be distributed at the server side for all the clients, see preferences.
