How to print from PowerApps a full List from SP

Question

HI

I am very new with PowerApps and I'm working on a project that at this point requires reporting, I follow the process fromhttps://www.c-sharpcorner.com/article/how-to-implement-print-functionality-in-power-app-form/. and I want to say that was the best step by step I have followed so far regarding PowerAppps. I ran the process however it gives me an error but I was able to get around it for now, but the data that pulls is from one row at the time from the list in SP, how do increase the data collection (array) to grabbed the whole list Data? Thank you again for any assistance
