So fun with good results!
Works great so far! Never used a sublimation printer or heat press before in my life and the shirt below is my attempt. The ghosting was totally user error and not due to the print. The set-up process was a bit long because it involved a 14 minute ink cycle, but the instructions walk you through every step very clearly so there were no issues. Follow them and you will be up and running in about 25 minutes. It did not come with paper as represented so be sure you have some on hand. The print quality is great from my perspective and from my shopping around, it's a great value for the money. There is little to no noise and it prints much faster than I was expecting.

Highly recommended! 🎨✨
This Epson sublimation printer has been one of the best investments for my small business. The print quality is outstanding—colors come out vibrant, sharp, and consistent on every project. Whether I’m printing on mugs, shirts, tumblers, or keychains, the results are professional every single time. Setup was easy, and the ink conversion for sublimation works smoothly. The printer runs quietly, and the prints dry quickly, which helps a lot when working on multiple orders. I also appreciate how efficient it is with ink; it lasts longer than I expected. If you’re starting a sublimation business or simply love crafting, this printer is a game changer. Reliable, easy to use, and delivers perfect prints every time. Highly recommended! 🎨✨
