Well Designed, Prints Clearly and Accurately, Software is a Bit of a Pain To Set Up
I've never used a printer in my entire life that didn't use finicky ink cartridges that are almost more expensive than the printer itself and need to be constantly replaced; this is a breath of fresh air, despite the dangers of spilling ink and making a mess. I found filling this with ink to be really easy, since you only have to pout the ink bottle in the correct port and leave it to fill itself, which takes about 10-15 seconds. the included ink bottles really only give you enough for a complete fill: You fill it, the printer set up charges the printer with ink, and the remaining ink in the bottles can refill about to the "max" line. Still, I really like this method. The top of the printer pops open like the hood of a car, to access the filling ports. It then has to be lowered down in two stages, presumably to prevent dropping the lid on fingers, though it doesn't seem heavy enough to cause major damage to adult fingers, and I have the printer elevated away from little fingers. This thing has the tiniest little LCD screen! It's a bit tricky on the Epson website to determine which software you need specifically. Obviously, my goal is to have a wireless printer for the entire home network. Some of the software seems specifically web-based, so you could theoretically print from work to a home printer, etc., though I balked at setting up or using an email address to send print jobs to. The wireless was annoyingly tricky to set up. I am still not sure if you're supposed to connect a computer and the printer to the wifi separately, or the printer first and then the computer would automatically recognize it, or what. I did successfully connect the printer to the wifi, but couldn't install some of the Epson software - it kept failing - but a quick test did allow me to print wirelessly, so I decided to just call it good and be done. Everything I have printed has been very clear and crisp. It could be a little darker and have more contrast, but that may be how I printed, or printing from pdf. It printed without jamming or sticking, and everything came through quickly and accurately, without leaks or streaks on my paper. I haven't tried the photocopier function though, since I mainly need it for printing and not scanning.

No automatic double sided. Bulky external paper tray
Set up was easy. I didn’t like the exterior paper storage. The whole printer was slick and stealthy until it got to that obnoxious tray. Set up was easy. Printer does not have automatic duplex capabilities you have to manually flip the paper to do double sided. I also didn’t think the printing quality was great.

Sorry, Brother. Epson smashed you.
I have been a long time Epson user. I have owned their printers, all-in-ones, movie projectors, and even a receipt scanner. In all cases, I have always found them to be the best performance per dollar of any of the big guys. There kind of like Panasonic in cameras where people may talk about some other big names, but what you get per dollar is always good from them. Somewhere along the way, I got disillusioned with companies charging me $60 per pack of ink. I'd get really mad when I couldn't print black text because red or something was out. For a few years, I gave up and just went black and white laser printer. The toner was dirt cheap, and my printing cost dropped to virtually nothing. But, my ability to pront pictures was gone. No more color at all. I'd have to go to a print business if I needed color copies. Well, this finally changed that. The EcoTank is a great design. The "Eco" stands for the economic cheap ink it takes, and the "Tank" refers to the big holding tanks for the ink and give long ink life. Epson probably makes the best ink, but many manufacturers sell inks for this printer. There's none of the stupid compatability issues with cartridges. It's 2026, so of course it all connects wirelessly over WiFi. It's wonderful. The only issue is that you might have to do a little more maintenance to keep it reliable. If you let old ink carts sit too long, you could just replace them. Here that isn't an option. I've seen Youtube recommendations that say you should probably print a color page every week or two, so factor that in to keep it running well. I love it. Five stars.

Solid Printer for Regular Use
I ordered this Epson EcoTank ET-2903 because I wanted a printer that did not make me feel held hostage by tiny ink cartridges. The refillable tank system is the main reason this printer stands out. Being able to see the ink levels on the front and refill from bottles makes the whole process feel less wasteful and less stressful. Setup was straightforward. Filling the ink tanks was easier than I expected because the bottles are keyed to the right color, so you are not guessing where each one goes. I did not have a mess during setup, and that was my biggest concern with a tank printer. Print quality is strong for normal home and office use. Black text comes out clean and easy to read, and color prints are bright enough for school projects, labels, recipes, forms, and casual photo printing. It is not the fastest printer I have ever used, but the tradeoff is lower ink stress and better long-term value. The wireless printing is convenient once it is connected. I like being able to print from my phone or laptop without moving files around. The scanner and copier are also useful for everyday paperwork, receipts, and documents. A couple practical notes: this is a rear-feed paper tray style printer, so plan where you are putting it because it needs some clearance. Also, it does not automatically print double-sided, so duplex printing takes a manual flip. For value, the ink tank system is what makes this worth it. If you print regularly and are tired of buying cartridges, this is a smart home office upgrade.

Epson EcoTank ET-2903
Epson ecotank are great replacements for standard printers. The fact that you get to use the ink bottles rather than the rip off ink cartridges that only last a little while is an amazing benefit. They print well and have a good print quality, so much so that we have one for normal printing and one for sublimation printing. I do all my printing wireless and have the rate occurrence that it has connectivity issues, like all printers. It holds a good amount of paper making refills less often Than the cheaper printers. To me it has been perfect for my small home business.
