My husband can’t print to our home printer due to firewalls on his laptop. So he always would have to email me the files to print. But now he can print from his phone using the phomemo app.At first, it wouldn’t print as the paper wouldn’t advance. But I pulled it when it was printing, and that seemed to do the trick. After it was done printing, I was able to rip it off the printer using the serrated paper cutter. It does leave a tiny serrated edge on the paper, so if that bothers you, you should use a paper cutter to cut the edge straight.The paper does roll up. I haven’t tried ways to get it to flatten. But if you need to scan it, I would tape it onto a flat piece of card stock and then scan. But I wouldn’t put this paper into a document feeder.The quality of the printing is very good and equal to our regular Epson inkjet printer, as you can see in the photo (the top paper is from this printer, the bottom one is from our Epson inkjet).They give you a small roll of letter thermal paper, and you can buy their brand of letter sized rolls for under twenty bucks (which is almost 100 sheets). So the paper is more expensive than traditional paper, but the portability of this printer is the positive trade off here.I can color on this paper with my alcohol markers as well as with pen. I haven’t tried pencil yet. The paper is glossier than regular printer paper and less absorbent. But for document signing, this should be fine.This also comes with 3 additional smaller sizes of paper rolls. I’m not entirely sure what the use would be for, except for maybe printing out receipts if you are selling items off site. Or maybe black and white (color is not available for thermal) prints of photos to use for play or scrap booking. My son has a toy thermal printer camera, but the resolution on that is horrible. I’m not sure if it’s the paper or the camera. But I’m pretty sure it’s the camera. Nonetheless, maybe I will use the smaller sizes printer paper rolls to print photos and use them in scrap booking.I kept this plugged in so I can’t speak to the battery capacity. But the online description says the battery should last around 160 pages, more than enough for most people. Overall, I’m surprisingly pleased with this printer.
