There were reasons for it even developers didn't understand. PDF is actually Adobe PDF and you had to use the Adobe PDF Creator to create PDFs. To be able to save to PDF by a 3rd party application would have meant licenses fees to Adobe. So some clever guys came up to "misuse" a printer library for PDF creation... Today in Libre Office, of course you find a button to _save_ directly to PDF. Not sure about MS Office though.
