As a long time self-appointed 'teacher' of computer stuff, I'll weigh in and offer you this explanation which is not technically exact, but I think may help you understand why this particular document is not printing properly:
- web pages are written in a language called html, where the content is described in a way that programs called 'browsers' can interpret. These browser programs then show the results of their interpretation onto the user's screen. Humans can then make the leap of turning the images on the screen into understandable information.
- PDF is a different way of describing what is represented on a page, and as such, it has it's own rules of telling when a page ends and the next one begins.
- Having a "Save as" function does not guarantee that the information will be delivered completely intact in the new format.
It takes well thought out technology to make the transition from one format to another, preserving the intent of the author and the readability desires of the audience.
I tried reading your pdf in my own favorite PDF program, and found that it is, indeed, formatted in such a way that there are gaps and that the page breaks that you observed on the screen are not replicated in the new document.
This doesn't help you with this individual file, but perhaps it will help your understanding.
Good luck!
