Reliable Everyday Printer Paper
Size: 1 Ream | 500 Sheets, Style: Letter (8.5x11)
This is standard plain printer paper for everyday home use, and it does exactly what it’s supposed to do without any issues. I have had no problems with paper jams, ink smudging, or feeding through the printer.
The paper is an average thickness, nothing special, but perfectly fine for printing documents. The color is white. It does not curl, and everything comes out clean and readable. It does not stand out in any particular way, but there is also nothing to complain about. Overall, it is reliable, consistent, and works well for regular home printing needs. I will buy again.

Love it.
Style: Ink
I love my epson workforce printer. I used to be a Canon person but once I got this printer. It changed my mind. So the ink is worth it. Especially in the bundle package. It may be a bit on the pricey side but it last me awhile. At least, in my opinion, it’s less expensive than buying them separately. Epson makes great stuff and glad I chose to stick with them. The ink is very good and looks great after it prints. Thanks to Epson for functionality, cost and efficiency when it comes you your products.

Epson Ink for the win

Love my epson printer and that I can order the ink just about anywhere. Ink is of good quality and depending on the amount you print, it seems to last a decent amount of time.

It's ink and it works.
Style: Ink
It's ink and it works. My Epson printer is VERY finicky and only wants name-brand ink. This is it. A little pricey but they all are.
