To restore the "Compress PDF" workflow to the Print dialog in OS X Snow Leopard install this package from an account with administrator privileges. This restores the Tiger functionality that Leopard ate.
If you are running OS X Leopard, install this older package instead.
Please ignore any instructions on installing this workflow that you may have read somewhere else. This new package obsoletes those instructions. When the installer says, "Finished," the package is installed and ready to use.
N.B.: This workflow works by compressing images. If your document does not contain images, or its images are already optimized, then your resulting PDF may be larger than one created without this workflow. In other words, don't expect that every PDF file can be made smaller; you must apply some thought to the problem beforehand.
To uninstall the Compress PDF workflow, remove the following file:
/Library/PDF Services/Compress PDF.workflow
If you installed an older version you may also need to uninstall these files (the tilde indicates your home directory):
~/Library/PDF Services/Compress PDF.workflow
~/Library/Filters/Compress PDF.qfilter
Download the compressed archive, expand it, and run the workflow to remove the all architectures except the machine architecture from the files you choose. For example, PPC will be removed on an Intel machine, and Intel will be removed on a PPC machine. Be careful not to shrink libraries that might be needed to run applications under Rosetta.
