Landscape printing from iPad Pro 12.9"

When I try to print a horizontal page from my iPad Pro 12.9" (3rd Gen) there is no function provided to choose portrait or landscape, so the "landscape" document prints as a landscape image on a portrait printout.

I am using an HP printer (HP MFP M148fdw), as well as some other HP printers, but the problem is that I can't find any way to get the document to print in a landscape mode.

Does anyone else have this issue?
