"File - Print...", "File - Print Preview" and "File - Print Setup" allow you to print the main window scene to a printer or file. It is useful to get high-quality wireframe or draft hard-copies of your project scene.
If you have not already done so in your desktop, the first thing you may want to choose is "File - Print Setup" to set up your system to recognize one or more printers connected to your computer. Refer to the Operating System help pages in case of difficulty.
"Print Preview" gives you a preview of the picture that will be sent to the printer. "Print" brings up the standard interface for printing documents.
Note: "Print" is a fairly time-consuming operation. For large projects, "Print" may take up to 10 minutes or longer to create a file for the printer.
