I want to save an image opened in Gimp in PDF format. But when I click "Save As", the closest format to PDF is PS. I later learned that I can click on "Print", and then select "Print to File" in PDF format.
I recall similar things has happened before with other software as well, i.e. saving to PDF format is not available, but printing to PDF format is. So I wonder why is it that way? Why is it different for PS format?
