The photo lab didn’t accept regular flash drives and only reads from outdated memory cards. I was frustrated at first but then I purchased a cable that allowed me to print pictures from my laptop using the Epson Picturemate. The photos are BEAUTIFUL. So much better than CVS printing.
Produces great photos. Ink and paper a little expensive, but I feel still worth it for the quality.
You must however run it at least once a month or the ink dries up in the nozzels.
