Beautiful, High-Quality Prints — A Great Photo Printer
I was looking for a good quality photo printer that could handle larger sizes, and this Epson XP-15000 really delivers. I’ve been so impressed with the print quality — the 13×19 prints come out beautifully: colorful, bold, and clean. Since it uses individual ink cartridges, it does go through ink pretty quickly, and buying all the separate cartridges isn’t cheap. But the results are worth it. The extra gray and red cartridges really make the colors stand out and give the prints a professional look. I’ve printed a number of images so far, and every single one has come out flawless. I’ve only had it a short time, but I’m extremely happy with it. Honestly, I do wish I had spent a little more and gotten the ET-8550 with the ink tank system, since it’s more cost-effective in the long run — but for what I paid, this printer still does an amazing job. If you’re looking for a printer for craft bags, chip bags, photo prints, stickers — this can handle it all beautifully. I’d definitely recommend it!

Easy to set up, print quality is excellent.
I've always been an HP guy but the ink has become so expensive that now I've got no choice but to look at other options. We needed a large format printer that could handle card stock and this printer after much research fitted the bill. We've done quite a few prints the the quality is exceptional. Set up was easy. The printer comes with a CD and quick setup manual, however we needed to go the Epson website to download the actual software suite to be able to print for our needs. The default drivers from the Windows auto installer were not sufficient because we were printing to a custom size of cardstock. After installation of the Epson suite everything was easy and we were off and running very quickly. WIFI connectivity from the printer was easy, the only thing that we had an issue with was the update from the PC however we updated right from the printer screen on the actual printer and it worked flawlessly. The printer has the regular 4 color cartridges as well as a red and a grey. The prints came out with great color accuracy and quality. After a few full page prints the black ink capacity was going down faster so we will purchase extra black ink first just to have it on hand. Also have to say that the printer is very very quiet and we didn't realize it was finished on most of the prints. Highly recommended printer.
