Firefox no longer allow "print as selected". Why not? It's inconvenient to not have this ability.
I use this to print puzzles from the Detroit Free Press. The "print as selected" prints the puzzle in a nice size on the paper. Otherwise the puzzle is too big. This is something that has just been changed and is not for the good. If it's not broke, don't fix it.

Hello,
You can print a highlighted selection in Firefox by selecting the Print Range > Selection option in the print popup window.
This is described in the Printing a Web Page section of this article: How to print web pages in Firefox
If this doesn't give you enough control then I suggest using an add-on to enhance Firefox's built in features. For example the Print Edit add-on allows you to modify your print preview to select exactly what you want to print and how.
I hope this covers what you need. Let me know if not.
