NOW it works with Windows Niimbot App via USB
This is a very cool and high-quality printer for labels. It is different from the latest cheaper square and "Cat Face" thermal printers (that are useful as well). The quality of this one - B21S - is better thanks to a different type of labels, made specifically for it with multiple layers that protect the print and make the label scratch-proof. It works with a Smartphone App (BT Connection) and finally with the Niimbot Windows App via USB. Initially, due to some bug, the printer was not connecting to the PC App, but thanks to some intense debugging with Tech support, the issue was solved and now all the B21S can work with a PC with a wired connection. If you are one of the owners that wasn't able to connect to a PC, try again :-) . Very good value for the money. Be careful about the labels you buy: Niimbot has specific ones and the generic ones do not print very well: the machine accepts them, but they are fainter.
