Adobe PDF Print Driver for iOS
Need help correctly exporting your magazine or booklets? Guess what, you actually don't need to be hooked up to a printer to format your export! You just need this handy print driver. If you're working on a PC, chances are you can already choose this option, but for some reason, it was removed from mac in an iOS update. Adding this driver to your Adobe InDesign preset allows you to export a booklet using any size paper without being connected to a printer. Here's how to do it!
To export a booklet for saddle stitch print and binding, first make sure you have the correct number of pages. A saddle stitch book requires that the total number of pages be divisible by 4 (or an even number of spreads) in order to print and line up properly.
Here's the trick! Download this Adobe PDF Print driver. This allows you to export your booklet as a pdf, without choosing a printer so your size choices will not be limited. Download the zip file here, unzip it, and then drop the PPDs folder into your Adobe Indesign presets. On a Mac you can find that by opening Finder and going to Applications>Adobe Indesign>Presets and drop the PPDs folder there. That's it! (Don't take the file out of the folder or rename the folder. Drop into Presets as is! This is how InDesign reads drivers)
