In Mac OS X it is possible to print any document directly to a PDF file. This is particularly useful for storage and for emailing files. Please note that once a document has been saved in PDF format, it will be essentially a read-only document. This means that you will be unable to edit the PDF file, so remember to keep a copy of your original! Saving a document as a PDF file is easy and the instructions to save any document to a PDF can be found below.

1. To save a document as a PDF file, select "Print..." from the "File" menu located in the upper-left-hand portion of the screen. The "Print" entry may be located under a different menu, depending on the application.
3. After a few seconds the standard 'Print' dialog will appear. Click on the button located in the lower-left-hand corner, labeled "PDF". This will bring up another menu where you can choose from a few actions associated with creating PDF documents. Select "Save as PDF...". Note for 10.3: If you are running OS X version 10.3, the dialog will be slightly different - the "PDF" drop-down menu will not be present. Instead, click on the button labeled 'Save to PDF...' and continue on to the next step.
4. The standard "Save" dialog box will appear. Select where you would like to save the PDF document and click the "Save" button.
5. You will see the standard "Print" dialog appear that shows up while printing a document. This is because the application is printing to a file instead of using a printer. After the program has finished printing there will be a PDF document in the location you specified, ready to be used as you see fit.
