To correct this, if you do not have a real printer, simply add a fake one:

1. Go to the Apple menu -> System Preferences -> Print & Scan
2. Click the padlock to unlock if necessary
3. Click the + sign above the padlock
4. Click IP
5. Enter a meaningless Address (such as 127.0.0.1)
6. Choose "Generic PostScript Printer" in the Use drop-down list
7. Click Add, then Continue
8. An error will appear. Click continue, then OK

Now try and save the score to PDF once again. It should work.
