When I try to print black only from the iOS app, my DJ Plus 4155 will only print documents 5x7

[WannabeFunnyMan]

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.

It's VERY frustrating.

4. Tap Print.

   The Print Preview screen displays.

5. Tap the image to access the Transformation menu where you can resize and rotate the image.

6. After you resize or rotate the image, tap Done to return to the Print Preview screen.

7. On the Print Preview screen, slide up the panel that displays the printer name above the print toolbar.
