Project overview
Founded in 1942, Epson is a Japan-based leader in innovative printing and imaging solutions. To support its new printer models, the company was in need of specialized firmware and drivers. In collaboration with Hitachi Vantara, LARION handled drivers for Windows and Linux and created unit tests. Delivered under the ODC model with a DevOps approach, our team of 7 engineers used C++, Rust, Jenkins, GG Test and Embunit to complete the project in 6 months. The solution enabled hardware control, error handling, firmware updates, and multi-OS compatibility, helping Epson launch new printers on time and enhance the user experience
Challenge: Skilled developers shortage
Epson, in the process of incubating new printer models, needed firmware to efficiently control and manage the printer’s hardware functionality. However, they faced a shortage of engineers with the expertise to develop embedded systems for latest printer models. Without this critical technical support, the progress of their new product line risked delays
To overcome this obstacle, Epson collaborated with Hitachi Vantara (formerly known as Global CyberSoft) and LARION with us developing printer drivers for Windows and Linux, and to create comprehensive unit tests to ensure the solution quality.
Solution: Cutting-edge firmware
LARION delivered the project under the Offshore Development Center (ODC) model, following a DevOps approach to streamline development and operations. Over six months, our dedicated team of seven engineers worked closely with the Hitachi Vantara project manager, aligning with their software engineering processes. Our team took charge of driver development and testing, ensuring we met all quality and performance standards.
For the tech stack, we used C++ and Rust for core development and leveraged Jenkins to automate continuous integration and delivery (CI/CD) pipelines, supporting our DevOps practices. Regarding testing, we applied GG Test and Embunit frameworks to validate functionality and maintain high-quality deliverables throughout the project lifecycle.
The solution provided the following key capabilities:
- Hardware control: Managed communication between the printer’s hardware components, such as the print head, paper feed, and sensors, ensuring proper functioning.
- Error handling: Detected issues like paper jams, low ink levels, or print head malfunctions and communicated these problems to the user.
- Firmware updates: Allowed manufacturers to release updates that improved performance, added new features, or fixed bugs without requiring hardware changes.
- Multiple operating systems: Ensured seamless printer functionality across Windows, Linux, macOS, and mobile platforms.
Result: Powering exceptional user experience
The project was successfully delivered on time, contributing to the timely launch of Epson’s new printer models. Throughout the engagement, our team produced high-quality outputs, including firmware, drivers, and comprehensive tests, all of which exceeded expectations and ensured optimal printer performance. By implementing firmware improvements and robust error-handling mechanisms, we significantly boosted customer satisfaction, delivering a smoother, more reliable printing experience. Our commitment to quality and precision played a crucial role in enhancing the overall user experience and supporting Epson’s goals for their new product line.
