Abstract
Description
Technical Field
[0001] This invention relates to the field of printer simulation technology, and more specifically, to a virtual printer design method, device, and storage medium. Background Technology
[0002] In the research and development of modern printing equipment, the collaborative development of software and hardware is crucial. However, traditional development models face many challenges. On the one hand, software development usually relies on actual hardware for debugging, but hardware research and development and manufacturing often lag behind software development, making it impossible for software engineers to conduct effective testing and optimization before the hardware is ready. On the other hand, even if the hardware is completed, the actual testing environment is difficult to fully simulate various complex usage scenarios, such as extreme environmental conditions (high temperature, high humidity, high dust concentration) and hardware failures (nozzle blockage, guide rail movement error, paper jams, etc.). These problems not only prolong the development cycle and increase development costs, but may also lead to compatibility and stability issues in actual use of the software.
[0003] Furthermore, most existing printing equipment testing methods are based on actual hardware and lack comprehensive consideration of complex environmental factors and hardware characteristic parameters. For example, environmental factors such as temperature, humidity and dust concentration affect ink viscosity, media ink absorption and nozzle clogging probability, as well as the physical constraints of the printhead, guide rail and paper feeding system affect printing accuracy and efficiency. These factors are often ignored in traditional testing. Therefore, it is particularly important to develop a virtual printer design method that can provide a comprehensive and controllable virtual testing environment during the software development stage.
