ESC/POS Receipt Printer Emulator

🖨️ This app emulates a networked receipt printer to test your ESC/POS commands against.

About

• Windows application (WPF + .NET 6)
• Binds to a TCP/IP interface and listens for ESC/POS commands
• Logs commands and visually represents the resulting receipt(s)

👷 This is an unfinished experiment. Use at your own risk and keep your expectations low. :)
