Epson SureColor F170 Sublimation Printer Rocks!
Style: Printer & Inks, Style: Printer & Inks
TI’m a newbie at sublimation, and this is my first sublimation printer. I love it! I can’t wait to make more things! I like that it’s not too large, but still can print up to 8.5x14”. The quality seems to be really good, but I also don’t have any other printer to compare it to. This was my very first project! I’m very happy with it so far!

Works great as advertised
Style: Printer & Inks, Style: Printer & Inks
Working great so far! Enjoying starting doing sublimation work. A rookie a few weeks in and it's going well. Print quality is decent. Not having paper jam issues. Was easy to setup. I had to goto Epson and download a current print driver to get all the print properties and printer settings I needed. Was easy. After I installed the 2nd driver and saw it worked better, then I uninstalled the 1st epson driver. Helped allow for 8.5 x 14 page size and high quality. Just a few options needed that were not showing on the original print driver. Took me a few days to figure out what was going on. It helped with the quality of the prints after I got the better driver. So the end product is better also.

Prints great, wifi was an issue
Style: Printer & Inks
Got the printer a week ago and have printed something every day so far and the quality of the prints have been fantastic. Arrived and set up without any major issues, other than not being able to connect to my local wifi. Had to get an Ethernet cable to connect to it.
