Windows Desktop Application for 4x6 Shipping Label Generation and Printing

We are seeking a skilled developer to create a simple yet robust Windows desktop application for our dispatch team. This software will be used by a tire delivery business to efficiently create, preview, print, and save 4x6 shipping labels.

Key functionalities required:

*  Clean, intuitive, and keyboard-friendly data entry interface.
*  Integrated barcode generation for tracking numbers.
*  Real-time address validation to ensure accuracy.
*  A reusable 4x6 label template that can be customized.
*  Direct printing capabilities to thermal label printers.
*  Option to export generated labels as PDF files.
*  Essential fields to include: order number, tracking number, dates, product details, quantity, customer information, company details, logo integration, and custom footer text.

Technical and Usability Requirements:

*  The application must run reliably on current Windows operating system versions.
*  It should be designed for ease of use by non-technical staff.
*  A portable executable or a single-file installer is highly preferred for deployment.

Deliverables:

*  Complete, well-documented source code.
*  A brief handover document covering installation, configuration, and guidance for future customization.

We invite proposals that include your recommended technology stack, your approach to implementing barcode generation and real-time address validation, an estimated delivery timeline, and any relevant examples of desktop applications you have previously developed.
