Project Overview

I designed, developed, and deployed a custom label printing web application for a calibration company. This solution empowered their technicians to efficiently generate and print single or multiple labels using Brother P-Touch label printers, either locally or via networked devices. The application also streamlined the management of certification data, ensuring accuracy and traceability.

Key Features

Custom Print Handler: Developed a custom print handler that facilitated seamless communication between the application and Brother SDK for reliable and precise label printing.

Dynamic Label Printing: Supported both single-label and batch printing directly from a web-based interface, accommodating diverse use cases.

Local and Network Printer Support: Allowed users to print from locally connected printers or detect and connect to networked machines with attached printers, enabling remote and field printing.
Print Log System: Implemented a comprehensive print log to track print jobs, providing visibility into print activity for accountability and operational insights.

Certification Management: Built a system to manage and update calibration certifications, ensuring that changes or corrections could be applied without duplicating records.

Autogenerated Certification Numbers: Designed an automated certification number generation system to prevent duplicates and maintain consistency across records.

Customizable Label Templates: Provided a form-based interface for technicians to input calibration data (e.g., tech IDs, certification numbers, calibration dates) and dynamically populate labels for printing.

Technologies Used

Frontend: React, Tailwind CSS for a responsive and intuitive UI.
State Management: Redux for managing application state.
Backend: Node.js with Prisma ORM for database interactions.
Database: SQL Server for robust data management.
Authentication: NextAuth for secure user authentication and session management.
Print Integration: Brother SDK for direct printer communication and operations.

Impact

This application revolutionized the company’s calibration labeling workflow by reducing manual effort, improving accuracy, and enabling greater flexibility in how and where labels were printed. The combination of a custom print handler, print log, and certification management ensured that the solution was both reliable and scalable, meeting the company’s current needs while preparing them for future growth.

This project exemplifies my expertise in delivering tailored, full-stack solutions that integrate hardware and software to solve real-world challenges effectively.
