Problem identified
Where the bounding box of the zucchini image overlaps the text, it causes a skew (or what ever you want to call it) of the Impact font, and other fonts I tested too. This only happens to the layers below the zucchini image. If the zucchini image layer is moved behind the text, it doesn't cause a problem.
The zucchini image is an imported PNG file using the 'Place Image Tool'. I obtained that PNG from an internet site (not sure if that has anything to do with it).
However, if I export the image as a PNG, PDF, or convert the text to curves, it prints without any problems as a single or multiple images per page. My non-qualified opinion don't think this is a printer problem. Brother all in one pinter fax scanner MFC -J825DW. I do not have easy access to another printer.
