I know there is an option to "Save as PDF". However, sometimes, you don't want to "Save as PDF". You may want to "Print as PDF" (as it is in windows).

These 2 are different since "saving as PDF" simply saves the page as it is while "Printing as PDF" gives one the flexibility of saving as booklet, multiple pages e.t.c.

Also, "printing as PDF" enables one to save PDF forms that are not traditionally enabled for saving.

All these are important and standard features on the Windows version of the software.
