The CR673A Premium Plus Photo Paper HP is once again significantly higher quality than the HP Advanced Photo Paper. With 300 g / m² is quite heavy and feels so well again really classy on. However, it misses properly by my elderly inkjet printer (HP Officejet 8500A Plus). The picture quality is excellent: pleasant luster, deep blacks, rich colors. Lab-quality photos so not an empty promise, even from an office printer. What's really amazing is that the photo is printed on this paper are actually waterproof, no running, no paper curling! (Also under running hot water directly from the tap - I wanted but then even know!) This can then none of the cheap products that I had already tried!
