This could be plain software on any computer with network and a serial port. Not sure if the product is tied to RP hardware but it certainly wouldn't have to be. I work with thermal printers controlled by significantly less powerful hardware still running Linux, and still easily hit physical speed limits. I'd rather see this as a pure software daemon that can run anywhere.
