Questions, answered.

The essentials for installing, testing, and activating POS Printer Emulator.

Do I need a physical printer?

No. The emulator listens for RAW network-printer traffic and renders the receipt locally on your Windows computer.

Does it work offline?

Yes. Receipt capture, viewing, history, and activation-key validation all work locally without an internet connection.

How does activation work?

Enter your customer or company name, email address, and activation key in the app. A valid key unlocks the Full Version immediately.

Where is receipt data stored?

Receipt data stays on the local Windows device. Trial jobs are session-only; the Full Version keeps local job history.

Can I remove everything later?

Yes. The included uninstaller removes the application, Windows service, firewall rule, shortcuts, and application data.
