By default, each block diagram is scaled during the printing process so that it fits on a single page. In the case of a large diagram, this automatic scaling can make the printed image difficult to read.
Tiled printing enables you to print even the largest block diagrams without sacrificing clarity and detail. Tiled printing allows you to distribute a block diagram over multiple pages. For example, you can use tiling to divide a model as shown in the figure, with each white box and each gray box representing a separate printed page.
You can control the number of pages over which Simulink® prints the block diagram.
Also, you can set different tiled-print settings for each of the systems in your model.
If you enable the print frame option, then Simulink does not use tiled printing.
