Wiki Formatting for Screenshots and Steps - Good Appearance in Print

Problem: This book is a how-to and it has steps which contain screenshots. Each step has an initial screenshot. The steps are in a numbered list.

I want the step text (instructions) to appear immediately after the number, and the screenshot to appear underneath the text. However I don't want the screenshot to ever break onto the next page when this is printed or converted to PDF. That will almost always happen naturally.

Note: I'm just going to choose one situation, and be concerned about that. (Rather than the 50 ways you can print a wiki page.) I'm going to look at printing via collections, hopefully direct-to-PDF (without passing through OpenOffice). I don't care how the pages render when printed by any browser, or with other tools for PDF conversion.

WikiBooks uses a software called ReportLab under the hood to render the PDF. The "export to PDF" link from each individual page can be used to test functionality.

Filler Text

A little filler text so that the testing section below falls on a page break!

1. here.

   

   And an additional comment...

2. Next step text... follow these instructions after doing step 1! Here is another sentence about this.

   

3. And next step which of course comes after both steps 1 and 2.

   

4. Here's a step with some text output...

5. Another step -- going to repeat the image from step 1...
