I recently found out that this question - How print multiple independent pages in one print job?, which is tagged with linux, and currently, its only answer, both also apply to Windows. (The answer, which suggested to use
pdftk, will also work for Windows.)
To make the question more relevant to others (as suggested by the 'How to Ask' page), could I suggest an edit to this question to make it ask for solutions for Windows too (and add the windows tag to it)? Its current and only answer will still apply.
