HP Neverstop Laser Printers are the world's first toner tank, rapid-reload printers designed to help customers and the environments. Previously, replacing toner meant disposing cartridges and introducing plastic and metal waste into the environment. Along with the innovative Toner Reload Kit, customers can now refill the Neverstop Laser Printer toner tanks.

The CTSS (Continuous Toner Supply System) portfolio addressed several interconnected challenges: creating a user-friendly visual language that was both intuitive and cohesive with its environment, reimagined the toner refill process to be effortless and mess-free to shift consumer perceptions and counter traditional refill practices in emerging markets, incorporating more recycled materials and reducing plastic usage to boost sustainability, and optimizing processes to lower the overall cost of ownership.

All interaction points are conceptualized and tested across multiple regions, including both developed and emerging markets, to validate and refine them. This process ensures adherence to quality standards, minimizing service calls and returns.
