How to print just a section of a web page?

I now have IE 7, but even when I had IE 6 I never understood how to print just a section of a page (for example, just one answer to a forum question).

IE Help says to right click the section and click print and then in the print dialog box click selection and then print.

But when I click print I don't get a dialog box with selection in it. I get the print window with General and Options tabs. And under options, I cannot click "only the selected frame" in Print frames. It doesn't register.

 

In IE 7:

Highlight with your mouse the section you wish to print.
Right click the highlighted area, Print Preview
Change the Print Preview selector item from 'As laid out on screen' to the second choice: 'As selected on screen.'

Then print it.

 

Thanks. Works fine.
