With Mac OS X 10.6 "Snow Leopard," Apple introduced an entirely new architecture for print drivers. The new system is designed to provide greater reliability and timeliness in printer support by taking much of it out of the hands of printer manufacturers that, frankly, have never been great at supporting the Mac platform.
With such a major change, though, there were bound to be casualties, and one was Acrobat's Adobe PDF print driver. It simply stopped working. In response, later versions of Acrobat Pro 9 have entirely removed the driver and its associated PostScript Printer Description (PPD) file from Snow Leopard systems. In its place, Acrobat leaves a new "Save as Adobe PDF" item on the PDF menu of the OS X print dialog. And of course, we can still export direct to PDF from within Adobe CS applications like InDesign and Illustrator.
That's all well and good for general use, but it doesn't satisfy every case. For instance, Lightning Source, the POD printer I use for my books, wants my book cover files to be run through Acrobat Distiller, which means first creating PostScript files from InDesign. But without the PPD for Adobe PDF, I have no way to create PostScript for oversize pages like book covers. It should work to choose "Device Independent" instead, but it doesn't. (I've written more about this specific problem on my
Publishing Blog.) Users of InDesign's Print Booklet feature have likewise found themselves up a creek.
Fortunately, there are ways to recover Adobe PDF's PPD and make it permanently available to CS apps. Here's the procedure for CS4.
1. Find a copy of ADPDF9.PPD, the PPD file that the latest Acrobat Pro 9 versions remove. You might find it on a backup of your computer at Library > Printers > PPDs > Contents > Resources > en.lproj. (That's starting from the root of your system, not from your user directory.) You can also get it from the Acrobat Pro 9 app itself if you choose "Show Package Contents" from the contextual menu and then go to Contents > MacOS > SelfHealFiles > AdobePDFPrinter > PPDs > Contents > Resources > en.lproj. You might also locate a copy for download from the Web.
2. Place this file in Library > Printers > PPDs > Contents > Resources. (Again, that's starting from the root of your system.) Do NOT place it in the folder en.lproj. Though that will work too, it will move the file farther down on menus, making it harder to find.
3. Rename the file so that Acrobat won't be able to find and remove it again. I suggest something like "Adobe PDF 9.ppd". (That, again, will keep the file high on menus.)
For CS4, that's all you have to do. Now, when you go to print from InDesign and choose "PostScript File" as your printer, you'll be able to choose "Adobe PDF 9.0" from the PPD menu. (You'll see a menu item by that name regardless of what you named the PPD file.)
With CS5, things are a little trickier. InDesign's menu does not show anything from the Mac OS PPD folder unless it's a PPD in a current print queue.
One possible solution for InDesign is to add the PPD file directly to the app's support files. Go to Applications > Adobe InDesign CS5 > Presets. Create a new folder named "PPDs" (case sensitive). Then place your PPD file in this folder. You don't even have to rename it.
The trouble with this method is that you'll have to repeat it if you ever reinstall the program or install a major upgrade. And by then, of course, who knows if you'll be able to find these instructions. So, a better method is to set up the PPD file in a new print queue -- a
dummy print queue -- where InDesign can find it. Here's how.
1. Start by following the same procedure as for CS4, locating, installing, and renaming the PPD file.
2. Go to the Print & Fax pane in System Preferences and click on the plus sign to add a printer.
3. Select ANY connected printer from the dialog. Then for "Name," change what's shown to "Adobe PDF" or whatever else you like. From the "Print Using" menu, select "Other," and then choose the PPD file you installed. When you click "Add," you'll get a warning about installing a queue for a printer that already has one. Take a deep breath and click "Continue."
You will now have a print queue with the desired PPD associated with it, in addition to your original queue for that printer. You will
not be able to create PDF files with this new queue, but you
will be able to access the PPD from InDesign CS5. And that will enable you to create PDFs with pages of any size.
