Good color, but expensive
Style: Cartridge Ink
Frankly, as with other printers, I thought that I could use reconditioned cartridges with this printer. The first set I purchased was not recognized, thus I have had to purchase genuine products. The cartridges, also offering good color, do not last long. It's a trade-off between cost and quality. If you have to go to Staples from dire need, be sure to price match, for Amazon is $1 less than Staples. Staples will match Amazon. Overall, I try to buy from Amazon.

Big Print Outs Look Great With Epson Ink
Style: Cartridge Ink
So I paint and I'd been trying to find a way to print out large pics to aid me when I'm trying to get my shading correct. This ink is fabulous...the printer just does a great job. First I print one in color and the second in greyscale...it helps a great deal when working with the shading. Epson can even add a couple other color cartridges to get different effects. I'm very happy with Epson inks. They really made a good selection of colors to make prints look amazing. 5 stars
