If you have a Cricut you need this
Style: Starter Bundle
Just what I needed to compliment my Cricut system. Works great, colors are perfect, set up was a breeze, connected to my wireless instantly. Prints look prefect, not all wonky like some can. Value pack was definitely worth the extra $50.

Mi impresora
Style: Starter Bundle
I am very happy with my printer. The print quality is excellent; the colors are vibrant, and the details look crisp. That said, I must admit that I have faced a few challenges when adjusting the tones, but I believe that with a little more practice, I will master them. Overall, it is an investment I highly recommend for anyone looking to get started in the world of sublimation.

Prints beautifully
Style: Starter Bundle
Prints sublimation prints perfectly. Colors are bold and vibrant. The first printer I used was an inkjet that I converted to sublimation. Wish I’d gotten this one first. It’s a world of difference compared to the print quality. So easy to download the drivers to your computer. The printer setup is extremely easy, just follow the prompts. Then, just click and print. Paper tray doesn’t hold a lot, but then again you don’t want too much paper to sit in the paper tray, because it starts to curl around the edge if left to sit out too long. Depending on how much graphics you are printing determines the speed of printing.
