I’m not sure which version of InDesign first introduced printing Thumbnails like this, but even if yours doesn’t support that, your printer driver may have a similar feature of its own. Check the printer’s own dialog box by clicking “Setup…” near the bottom left corner of the Print dialog and dismissing the warning, then clicking “Preferences…” in Windows’s Print dialog that comes up (I’m not sure how to access this on Mac OS X, but I’m pretty sure there’s an easy way). For instance, on many HP printers, the feature you want is called “Pages per sheet” and has a drop-down offering 1, 2, 4, 9, or 16 pages per sheet.
There may be instances in your Adobe InDesign documents that you want to change the start page, by default the numbering starts at page one on the first page of your document but if you right click on for example page 2 you can select ‘Numbering and section options’ then you can click the button ‘Start page numbering at’ then type ‘2’ in to the box. this will snow start a new section on page two which will make page 2’s page number actually page 1. You can start new page numbering sections anywhere in your Adobe InDesign document. 

If you want numbered headings to be underlined, but do not want a line under the number, it can be difficult if you don't know how it works. This is because by default, the format of the number follows the format of the text that follows it. For example, let's say you want to underline a paragraph in a Heading 2 style.
