what third party app do i need to view my imessages online with Windows

Did you have any luck figuring this out? There must be some way to send and/or print a text chain without screenshotting it one by one. I need to print / save a message chain and I cannot figure out to do it easily.

If you are wanting to see messages that were sent with Apple's Messages app/application, there isn't a Windows compatible application that can do that.
