This is like one of those little label makers, but is capable of printing on a4 width rolls of paper. The print quality is pretty decent for a thermal printer (not mind blowing, but certainly works well enough for documents and such) and the setup was a breeze. the app isn't great, but I found that this printer works with a few different apps on the market, making it a very versatile printer for your kit. I will say though, it's a fair bit larger than some of the other printers I've used in this segment... for example, both peripage and phomemo make a similar a4 printer and they are both much more compact. Still, if that's not a deal breaker, this is an awesome little printer that will handle your monochrome print needs with ease.
