The best thing about this product is that it can be used in any location, anywhere in the world. It's very easy to use and one of the best features is the security. I don't have anything negative to say about this product. It has been working great for us and we haven't had any issues with it. We are able to print documents from our computer or even an iPad and send them to multiple recipients at once. The ease of use and the support when you need it. The mobile app is great and the support is fantastic. I have not found anything I dislike. We have been able to implement a real time print queue and we have used the mobile app to manage the printer and print queues remotely. The printer has been very reliable and has not had any issues. We have also been able to use the mobile app to manage the printer remotely.
