Easy install
Style: Ink
Reliable, vibrant, and easy to install. The print quality is crisp and professional, which is important for my presentations, workshops, and business materials. No smudging, no issues — just dependable performance. Definitely worth keeping on hand.

Hate the Price, but love the ink.
Style: Ink
I totally hate the price of printer ink, mostly when it dries out when not in constant use, but I purchased generic and my printer would not let me use it and i have avoided the firmware update. So back to buying epson ink. It worked the minute i loaded it into the printer. Epson ink is great. it was great color and quality. Just hate the price tag.

Pricey but they work
Style: Ink
Pricey but the remanufactured ones either don't work at all, or they work for a short time then go belly up...
