Handles Photo-Quality Prints, Versatile Connectivity
Color: Black, Style: ET-2800-B, Pattern Name: Printer, Color: Black, Style: ET-2800-B, Pattern Name: Printer
I've had this printer for a whole year now. I was on a severe budget, looking for a photo-quality printer that didn't require Wifi in this digital age- because I quite frankly can't afford my own Wifi connection. My rink-a-dink laptop had to be set up with the software at my library, and an extra cord purchased. All that said, I mostly print from my phone, because the software app is a bit easier to ensure that I get the highest quality setting. Laptop loves to be a snot about it. The blutooth feature, or "wifi direct", has a way about it, and as soon as you figure out what it wants, it gives minimal problems. It functions exactly as if a printer had wifi on it, believe it or not. What sold me on this model was the ability to do all of that, and adjust for different situations, seeing as other brands DEMAND constant wifi connectivity (lookin' at BROTHER, maybe Canon, too), and the long lasting ink tanks- I've printed hundreds of pages, and being a gothic/horror artist, at least a good part of the time, black is the only color even half gone. What horrified me the most about printer-shoping dropping a lot of money (hundred plus is a lot over here, man) and not getting the prints to look like my work. Well, fear not. The attached pictures are why I made this review, to hopefully ease the anxiety of others. I make digital paintings, and use high DPI for high quality, and also the cutest micro-stickers you've ever seen. Prints come out clear, even if they can sit in the tip of my finger. Yes, there are probably better printers. Maybe they're faster, and have even better connectivity, and have more bells and whistles. I specifically did not want to pay for those things, so, I'm very happy there's options. It's not perfect, no, because every now and then, I get what I call a "special edition", where my printer has decided to multi-color barf out the last third of the page. One time it randomly printed in black and white. Well, that's no big deal, my stuff tends to look great in monochrome. Every now and then I get a low quality print; things just look a bit fuzzy. I'm not happy about that, but, you clean the heads, and print something simple and toony, and it has never done it twice in a row. Alignment has been off only one time, and I put the printer away after every session. It occurs to me that people pay good amounts of money for printers that do that sort of thing anyway, so... Printers gonna printer, no matter where you try to hide. Overall, I'm happy and relieved. I hope it lasts me a good long time. (Streetratt on Kofi, by the way.🖤 )

Amazing value and performance — perfect everyday home printer!
Color: Black, Style: ET-2800-B, Pattern Name: Printer
After lots of research and comparing ink costs, I finally purchased the Epson EcoTank ET-2800 Wireless Color All-in-One Cartridge-Free Supertank with Scan and Copy and it has been one of the best tech investments I’ve made for my home setup. Whether I’m printing documents, photos, homework, or creative projects, this printer delivers consistently reliable results without the usual stress over ink costs. Right out of the box, setup was surprisingly easy. Epson’s app guided me through the wireless connection, and within minutes the printer was connected to my Wi-Fi and ready to go. The initial filling of the ink tanks took a few extra minutes, but the included bottles were clearly labeled and simple to use without mess. The print quality has exceeded my expectations for an all-in-one home printer: - Documents: Crisp, clean text — perfect for school assignments, work documents, letters, and recipes. - Photos: Bright, colorful prints with decent detail (especially when using good-quality paper). - Graphics & Crafts: I’ve printed worksheets, planner pages, labels, and even small art pieces — and everything looks sharp and vibrant. - The speed is solid for its class. It’s not a professional office machine, but it doesn’t feel slow for everyday use. Cartridge-Free Ink — Game Changer This is the real highlight: - Cartridge-free Supertank System: Instead of tiny cartridges that run out in no time, this printer uses large refillable ink tanks — which means massive savings on ink long-term. - Low Ink Cost: You really feel the savings after your first few refills. I used to go through cartridges quickly, but now I only refill every few months — and even then, it’s affordable. The included ink bottles provide a ton of pages, and you can easily track levels through the transparent tanks so you’re never caught off guard. The wireless setup works smoothly. I can print from: - My phone (via Epson app, AirPrint, or Google Cloud Print) - My laptop or tablet - Directly via Wi-Fi without cables No more plugging USB in every time — super convenient. The scanner is quick and easy to use: - Scan photos - Scan documents straight to email or phone - Make copies without touching a computer The scan quality is clear and accurate — ideal for digitizing receipts, forms, or school worksheets. Pros: - Huge savings on ink long-term - Excellent print quality for text and color graphics - Easy wireless setup and mobile printing - Transparent tanks — see ink levels at a glance - Scanner and copier work well for everyday tasks - Quiet operation compared to older printers Minor Notes - Initial setup takes a bit longer because of ink filling — but it’s worth it. - Photo prints are good for casual use, though super high-detail photography will still look better with dedicated photo printers or labs. - No automatic document feeder (ADF) — so multi-page scanning requires manual pages. The Epson EcoTank ET-2800 has transformed my printing experience. It’s affordable to run, produces great everyday prints, and the wireless features make it super convenient for the entire household. If you’re looking for a home printer that won’t drain your budget on ink, this one is absolutely worth it. Whether you’re printing school documents, work files, planners, photos, or craft projects, this printer does it all with ease — and saves you money over time. Highly recommended for home use — practical, efficient, and budget-friendly!

Excellent Investment!
Color: Black, Style: ET-2800-B, Pattern Name: Printer
I have had this printer for two years now. I purchased it to do invitations and signs for my Daughter's baby shower. I designed an invitation, printed more than sixty copies with address labels, return address labels, numerous signs, games and raffles tickets. I used it again for the Baby's 1st Birthday same amount of items. I have not had to fill the colored ink in over 2 years. I have filled the black. My husband also uses it for work and I've printed several other projects including pictures. Everything has always exceeded my expectations. For the price you get excellent quality. I find the software easy to use and update.

Light Weight & Durability
The Universal 65W USB-C Laptop Charger works great and charges fast. I used it with my Chromebook and another USB-C laptop with no problems. The cord is a good length, and the charger feels sturdy and reliable. I like that it works with many brands like HP, Lenovo, Dell, Acer, Asus, Samsung, and Google devices. Great replacement charger for home, office, or travel use.
