If you can make it work so people can be able to print from the interface design that would be fantastic

I have found out that when you do a custom page in Page Design you would be able to print as many pages as you like but one thing that I didn't find is how you can print from the interface design.    

I have just landed on this function today it worked for me! are we allowed to share codes here, if so share yours we can see what’s the issue is!
