The paper itself is great but HP has a new feature called Auto Sense. This is a small barcode on all 4 corners on the underside of the paper. But when they packaged the paper, the ink on the bar code wasn't dry yet so the barcode ink has dried on the print-side of the next sheet in the pack. After printing you can still clearly see these marks because the printer ink doesn't stick to the already dried bar-code ink. The marks are especially visible if the corner of your photo is one color, like the sky.And on Premium Plus photo paper at 0.70 per sheet I'd expect better.I'm returning mine.
