We have used SATO printers for many years. The current models that we use are the CL4NX and CL6NX (https://www.satoamerica.com/products/printers). I don't recommend buying the CL6NX with the wider print area if you're not going to use it. We have had wear issues on the printhead and other parts when running narrower labels in the wider printer for an extended period of time.
