Scans OK, but....

It may be my inexperience, as I just downloaded the app and tried to use it. I was able to scan from my MX922 to my iPad Pro, but cant seem to print a thing. If I select Print Document, and select a pdf, the error message says "Cant print document." Thats a disappointment! If I choose a Word document, the app displays (and prints) a blank page. Thats just as bad. However, I was able to scan both B/W and color documents...BUT not with the document feeder. There seem to be a lot of bugs with this app, but I can scan which is why I got it. I can already print directly to the MX922 using the WiFi function.
