I do lots of printing as a teacher and go through lots of ink. Staples has a reward program that I use and get money back. Now that's a deal. I have no issues whatsoever with my ink. Keep a fresh cartridge handy at all times to be prepared for that moment when the old ones are gone. The 4 pack is great because you can just replace the cartridge that is empty and you get the black cartridge along with the color in one box. They are easy to replace and seem to last longer than older cartridges lasted. The color and black printouts look superb. Never any issues at all.
I ordered two ink cartridges and they both came on the same day but in different boxes? I believe this was a waste of postage and supplies. why not put them in the same box to save on supplies and shipping? they were ordered on the same day and from the same company!
The HP inks are always of the highest quality however like anything of high quality comes a high price tag. I don't know how they do and obviously neither do their competitors because HP seems to have the magic formula when it comes to their inks. There is a big difference between HP inks and other brands I have seen this first hand in many cases at work and at home. I learned this the hard way which is why you don't have to if you take my advice. I have tried just about ever short cut on inks from refilling to off brands and there is just too much to lose when it comes to quality printing or just any printing. From smudges to leaking and even causing problems with the printer and it's components! I learned my lesson please don't learn yours the hard way. If HP could only lower their price points on these they would be 5 of 5 Stars!
