Our Standard Cartridges.
Style: Ink
These cartridges are the only ones that work for our Epson printer. in the past, I have tried 3rd party units with various degrees of success. Sometimes they will work and sometimes not. They are less expensive up front but, in the long run, I am going to stick with the genuine Epson product. They are the same price everywhere that I have shopped, so we purchase them from Amazon because of the free shipping. The Epson cartridges just work in our printer.

In a busy auto body shop, we print a lot of paperwork every single day. Between repair estimates, insurance documents, invoices, work orders, and customer paperwork, having a dependable supply of printer paper is a necessity. Amazon Basics Multipurpose Copy Printer Paper has become one of those products that we always make sure to keep in stock.
The quality has been excellent for our everyday office needs. It feeds through our printers smoothly, produces clean, sharp documents, and we haven't experienced the jams or inconsistent performance that can sometimes come with lower-quality paper. Whether we're printing simple forms or detailed estimates, it gets the job done.
Another reason we continue to purchase it is the value. Running a business means paying attention to operating costs, and this paper offers a great balance between affordability and quality. We go through a large volume of paper, so being able to save money without sacrificing performance is a huge advantage.
I also appreciate the convenience of ordering it through Amazon. Instead of making extra trips to the office supply store, we can have it delivered directly to the shop and know that we'll always have enough on hand when we need it.
Overall, this has become our go-to copy paper for our business. It's dependable, high quality, and priced competitively.

Great paper good price
Size: 3 Reams | 1500 Sheets, Style: Letter (8.5x11)
This is a solid everyday paper option that does exactly what it’s supposed to do.
The packaging was good—everything arrived in perfect condition with no bent corners or damaged reams. It’s nice not having to deal with warped paper right out of the box.
Printing quality has been consistent. I’ve used it for both home and work printing, and it feeds smoothly through the printer without jams. The brightness is good too—text comes out clear and sharp, and colors look decent for standard copy paper.
Overall, it’s reliable, good quality paper at a fair price. I’d definitely buy it again.

Nice daily use paper for ink jet printers. A good white rating too. OK for occasional color
Size: 1 Ream | 500 Sheets, Style: Letter (8.5x11)
Very good paper for daily use on ink jet printers. Good price, fast deliver, and packaged well. It even works well for color printing but not what you want for high quality glossy color prints.
