Review on MFP inkjet HP Ink Tank 315, color, A4, black by Adam Kardasz ᠌

I chose a printer with pigment ink, this was the most important criterion. Everything else was secondary. In the description of this printer it is written pigment ink. We go online and read: Water-soluble ink is an aqueous solution of organic substances. They are low cost, allow to achieve high realism of color reproduction, but are unstable to ultraviolet and water, which does not allow the printed image to be actively exposed to sunlight and moisture. Pigment inks - unlike water-based inks, they use a solid pigment (very fine particles of solids) as a dye. These inks are more water resistant than liquid dyes. When the ink escapes from the nozzle of the print head, part of the solvent evaporates, upon contact with the paper, the remaining part of the solvent impregnates it, and the pigment remains on the surface of the paper, after contact with the paper, with the participation of air oxygen, the ink coagulates (folds) with their transition to an insoluble state, which makes prints water-resistant. So this same water resistance was very important to me. With false information, you are not just misleading buyers, you are deceiving. Selling a product that does not meet the declared characteristics. As a result, the money is spent, the printer seems to be available, but the problem has not been solved, you still need to purchase a printer. And the question is - what should I do with this printer now?
