The Adobe PDF Printer is not available or is unusable from Mac OS X Snow Leopard (v10.6) to Mac OS X Mountain Lion (v10.8).
If you upgrade from Mac OS X Leopard (v10.5), Snow Leopard (v10.6), Lion (v10.7), or Mountain Lion (v10.8), the Adobe PDF Printer isn't removed.
The Save As Adobe PDF command appears in the PDF menu.
Security features in Snow Leopard and later editions that disable the Adobe PDF Printer. Adobe Acrobat 9.1 Pro and later editions up to Acrobat 11.0.x Pro remove the Adobe PDF Printer. Add, they add a Save As Adobe PDF command. Customers using earlier versions of Adobe Acrobat in Snow Leopard cannot use the Adobe PDF Printer.
Technical changes in Mac OS X Snow Leopard (v10.6) and the later editions prevent Adobe from delivering a PostScript-based printer module. However, the new PDF workflow takes advantage of the PDF-based printing architecture already present in Mac OS X. By choosing Save As Adobe PDF from the PDF menu, Apple-based PDFs are converted to Adobe-quality PDFs using your JobOption settings.
The benefits of a PDF-to-PDF print workflow include the following:
Users of non-Adobe PostScript-based publishing applications cannot print directly to Adobe PDF, and must use another PDF creation method.
Some versions of some Adobe products, such as InDesign and Illustrator CS4 or CS5, don't support the PDF menu in the Mac OS X print dialog box. For those cases, either save as (Illustrator) or export (InDesign) to a PDF file. Or, print to PostScript® file and open that file with Distiller, Acrobat Professional, or Apple's Preview application.
