To continue the evolution of thermal inkjet printing, key technology developments are needed. These include the ability to print text output as fast as laser printers, determining and delivering realistic color print speeds for the consumer, lower cost of the printer and the output, and finally, realistic natural images on a wide selection of medias. In this paper, the resolution and quality needed for different types of printing are reviewed. The technical feasibility is assessed in terms of enabling subtechnologies that need to be developed to support the ultimate application goals for each type of printing. Key developments required are outlined and the underlying technical challenges that must be met in order to enable faster text, faster graphics, and high-quality image output are listed. Large arrays, higher resolution, and the need and methods for producing variable spot size from one nozzle are reviewed and assessed.
