Printing is great, wifi is a problem (I figured out how to make it work!)
Color: White, Style: ET-2800-W, Pattern Name: Printer
I was on the fence about buying this printer because most of the 1 star reviews all said the same thing... "The Wifi would not work" So I followed the instructions, Turned on the print, downloaded the IOS app, connected to the printer via Bluetooth, installed the ink, initialized the printheads. While that was going on, the app asked me to setup the wifi. a List of SSID's came up and I selected the one I wanted. I put in the password and it connected and the icon on the printer turned blue. I have a Unifi setup and I could see that the printer connected to access point #3 @ 2.4ghz and got an ip address. I locked the IP address to the printer. (For my instructions to work for you, you need to make a reservation or lock the ipaddress that your DHCP server provided to the printer. ) If you don't do this, you will get a different address every time you turn the printer on and the computer and app will not be able to find the printer. When the initialization was complete, the app on my phone said it could not connect to the printer. I decided to try to connect to a computer and come back to the phone app. I downloaded the software package from Epson and ran it. When it went to connect to the printer it could not find it and brings up a list of troubleshooting steps that are not likely to do anything. There are videos about this problem and they are all useless. I am an IT professional with 26 years of experience. I am not going to unplug the printer and wait five minutes, I am not going to re-boot my router, I have a Unifi network environment with over 150 devices connected... (I have great wifi coverage, I am not moving my printer anywhere) My network works just fine, this printer is the issue! So at this point, I know that the printer IS connected to my wifi and it got an IP address. This is not a wifi problem as everyone seems to think it is. It is an issue with the Epson software. I decided to try to install it via the windows printer installer. I selected install via TCP/IP and put the ipaddress that my Unifi system provided to the printer. Windows found the printer and since the Epson app had already installed the drivers... just asked me what drivers I wanted to use. The ET-2800 showed up on the right hand side of the screen. I selected it, it installed and I was able to try a test print. It worked fine. I can print from my computer to the printer via the network. Next was the phone app. The phone app has the option to find the printer via the IP address. I put the IP address in and it found the printer. The phone app works now too. So, It took me some time to get this working, it should not have taken any time at all if the software worked correctly. The printer is really nice, it is a shame that the software is so bad when it comes to connecting to the printer. So if you decide to buy one of these printers, save yourself the headache and just install using the ip address, it is quick and easy that way and it just works. I would have just purchased an HP printer, but I did not want to deal with all the issues of their subscription ink service. I feel like the cost of ink makes this printer worth the hassle of getting it to work.

Premium Print Quality Meets Economic Design
Color: White, Style: ET-2803, Pattern Name: Printer
I am very impressed with the manufacturer quality of this printer. It feels durable and well-engineered. The print quality is equally excellent; colors are vibrant and text is sharp, easily meeting the standards I need for both documents and photos. Moving away from cartridges is a huge win. The ink lasts incredibly long, and the refill process is clean and simple. The only thing I miss is a USB port for printing directly from external storage. My old HP printer had this feature, and it was extremely useful for printing files quickly without a computer. I wish this Epson model included that same convenience. Final Verdict A high-quality, reliable printer that produces great results. If you don't mind the lack of a direct USB drive slot, it’s an outstanding choice for home use.

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.🖤 )

Great functional printer
Color: Black, Style: ET-2800-B, Pattern Name: Printer
This is a great basic printer for my office. We have a higher model in our main floor office but it is older. The setup is fast and easy and it prints well. I set it up right from my phone. The picture quality is great and it prints quickly. It is so convenient and was the right price for what I need.

Cool Texture, Great Product, Notable Cons, Still Recommend
Model: Tab S11/S10 Lite/S10 FE/S9/S9 FE/S8/S7
AMAZING PRODUCT! I've never used a "paper-like" screen protector, but this one applied perfectly and was easy to use! (just follow the instructions!) no bubbles, just one single speck of dust (my own fault - sigh). It creates a very strong "matte" effect and feels cool to run your hand over (very paper-y) CONS: -The fit was SLIGHTLY big for my new S11 tablet, (each corner went RIGHT to the very corner of the tablet ALMOST going over the lip-this was just the corners of the protector and not the edges, which I found weird. IMO, its too close for my own comfort, but it still works none the less, and I've managed to use a case with it too with only minor corner lift). -The texture of the screen protector definitely distorts the pixels slightly, its just something to get used to, and probably something you'd have to see yourself, for if it would bug you or not. -It collects fingerprints like craaazy but they also wipe off craaazy easy too....sooo not fully an issue? just surprised me. Overall, for the money, I still recommend getting this protector if you're at all interested in a "paper-like" finish!
