  1. Rated 4 out of 5


    Awesome! so much easier to use than I expected. The datacom app really makes my installations go much faster. Plus the supplies are much less expensive than what I was paying with my other printer.

  2. Rated 5 out of 5


    Linkware live in the datacom app makes my labeling on site so much easier! Saves me a lot of time.

  3. Rated 3 out of 5


    When we purchased this printer we were not aware that it is not capable of doing half-cuts. It was very disappointing as that is the main function we purchased it for. Other than that it was a nifty printer.

We hope that despite the LW-PX400 not having the half-cut function that the printer will be of use to you, but if not, please feel free to reach out to our customer service department and we’ll do whatever we can to make sure you are taken care of.
