right at the top, click "File", and from the dropdown that appears click "Print..."
In the box that appears there are some choices, but they are all straightforward... which pages, (of the pdf) to print, all, or just some... just odd pages, just even pages, etc...
It's quite easy.
Also, if on the menu bar you choose "View" and then "Toolbars", make sure the choice "File" is ticked. This means the "File" toolbar will be shown which has an button/icon for a printer. (it will be "greyed out" and not useable unless there is a pdf document open). Clicking this button brings up the dialogue box mentioned previously.
