When using the Moodle HTML editor and viewing the "finished" chapters and whole book within Moodle, the formatting looks quite fine (e.g., font types, font colors, background font color). However, when going to "Print this chapter" or "Print book", there is extra "white space" (such as a full line break) as well as some of the coloring seems to "bleed over" into other paragraphs.

Checking the HTML code within a web browser (IE and Firefox) which was drafted using LibreOffice and even exporting into PDF format, things look fine and correct.

Attachments show an example of what is seen within Moodle and when one "Prints this chapter" where the background coloring has an extra line of "white space" added.
