I've used this ink for everything including printing photos, letters, coupons, and various Word documents. For all of these tasks the quality of printing has been excellent. The colors are true to life and the black is very dark.
The printer lets you know when you are running low on ink, both the color and the black, so you don't end up running out at the last minute. I find this feature to be very useful as I use to run out of ink at the most inconvenient times. As far as running out is concerned I've found these cartridges to be very long lasting. As mentioned before I use my printer for a variety of tasks and have found that I can use the same cartdridge for several months without having to replace it. When it does need to be replaced the cost is much lower than that of other cartdridges.
This printer cartridge is an excellent value for high quality printing!
