Print on a separate Blink window, or elsewhere than STOUT

I am writing UI using blink and Interact. I am fairly new to the use of tasks and CSS, so maybe my problem is actually fairly easy. During different operations, I use print to write messages such as “wait for…”, “all good” and so on. I would like to integrate these messages in a dialogue box in my UI, still using print so that I won’t have to add another object as an argument of all my functions. Is this possible or I am approaching the problem in the wrong way?
