Printing from Photoshop Express

[Mr. Lucas]

I installed Photoshop Express on my iPhone 13 Pro Plus a couple of days ago, and I like what I've seen so far. I've applied a filter to one (and only one) of my photos, and I'd like to print it at 8" X 8" (square) for framing. That sounds simple, and I get into the Print dialog with no trouble.

However, I am not happy with the results. I've made three prints on 4" X 6" paper, and all three have come out filling the entire paper, borderless. The picture is of a large wheel, and these prints have lopped off the top and bottom. Oddly enough, the preview in the Print dialog looks exactly like what I want—a square photo braced by two little white bands on both ends—but that's not what I get. See my screenshot.

My printer: HP Envy 7855.

I hope someone here can walk me through what I'm missing.

Well ... I may have stumbled onto a solution to my own problem. Just now I printed the same photo from Apple Photos on my MacBook Pro. The results were exactly what I expected. So it appears the problem is not with Photoshop Express, nor with my printer. The problem I described in my original post resulted from shortcomings built into the print dialog on my phone. It simply does not know how to handle the printing of anything other than a conventional 4" X 6" photo. Is that about it, or can anyone point to another solution?
