Problem printing certain email (for work) from chain of conversation

Hi

I have attached an email example of what im about to try and explain.



As you can see, this email has a chain of conversations going on.

I want to print the conversation where i have marked 3. I dont want any other conversation involved in the print. How do i do this?

I have tried expanding the conversations >> click the down arrow where i have marked 1 at the top right of the picture >> then clicking on print. But no luck because i still get other conversations printed.

Can you notice each conversation is divided by a light grey line where i have marked 2? I thought this would seperate each conversation so you can print one conversation without involving others. But this does not seem to be the case.

When i try and print, it involves the conversations above and below the conversation i want to print.

How do i solve this problem? I need this for my work.
