Print Line Streaks

The bands in the picture seem to be evenly spaced, and don’t seem to be tied to a specific gradient direction. That suggests the bands are not tied to the document, but possibly to the printer.

If this is your first inkjet printer, have you run a nozzle check recently? Clogged nozzles can result in regularly spaced unwanted bands in the print, because they contain rows where ink should have been laid down but were not. If a nozzle check shows one or more clogged nozzles, running a print head cleaning cycle could clear it up.

There is a less likely chance that it’s a moiré pattern caused by the document resolution vs the printer resolution. What are the pixel dimensions (width in pixels by height in pixels) of the document?

Does it change if you change the print quality setting? Although Standard should be good enough.
