To print a mind map, click on the Print button in the bottom right corner of the mind map editor. This opens the Print options.
In the Print options, you can select your desired page format (A4, Letter, Legal etc.) and switch between landscape and portrait mode. MindMeister will automatically create printing slides for you, but you can easily create additional slides, move them around and resize them as needed.
Printing your mind map across multiple pages is particularly useful if your map is very big and complex. In this case, forcing the whole map onto one single page can make it difficult to read all its tiny details.
Finally, choose whether you want to print the mind map's background, too, and then click on the blue Print button to open the standard print dialog.
