When I print from the iOS HP Smart app and choose black only, all documents default to 5x7 and I cannot find a way to change it. I tried printing from multiple different apps and got the same result. In those apps it doesn't matter what I choose for paper size, it prints in 5x7 if it doesn't give me a paper mismatch and not print at all. Alternatively, when I print in color I can print anything 8.5x11.
How can I change this back? It seems like a waste to print black only documents in color.
