Update (12/09/2016): It's now possible to specify any custom page size you wish!

The new script dialog, with the custom page size option

One of the biggest differences between using Adobe Acrobat on a Windows computer and on a Mac is that the virtual Adobe PDF printer is not available on the latter. This means that the option to print a multiple pages from a PDF file to a single sheet is not available to Mac users, which is a shame as it is very handy when you want to create a summary or a hand-out.

This problem is now easily solved using my latest tool, which allows anyone to print as many pages as they want to a single page. And after printing you can save the generated file as a new PDF, so you don't have just a physical copy of it, but a digital one as well!

Here's how it works. After purchasing and installing the script a new option is added to the File menu, just under the Print command (the screenshots below are from a Windows machine, but it will be the same on a Mac, of course):

The new menu item under File (click to enlarge)You're then prompted to select which pages to print, as well as the layout of the generated pages, their paper size, whether to include the page borders on the print-out and whether to close the new file after it's printed:

The settings dialog of the script
When you press OK in the dialog above, the new file is created and the Print dialog is automatically opened, ready to print the newly created file (notice that there are 4 original pages on the first page in the preview):

After you printed the file, if you didn't select to close it automatically, you will be able to save it, edit it, sent it to others, etc., just like any other PDF.
