Loading the community impact total…

Illustrative estimate based on 3⅛-inch thermal paper, an average receipt length of 6 inches, and 2.5 g CO₂e per receipt. Actual receipt length, paper production, and disposal impacts vary. Many thermal-paper coatings can also complicate recycling.

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?

Receipt capture, viewing, and history work locally without an internet connection. Account linking and entitlement synchronization require a secure internet connection.

How does activation work?

Select Link This Computer in the app, sign in to your verified Customer Portal account, approve the computer, and select an eligible license. The application applies it automatically without a reinstall.

Is the paid software a subscription?

No. Lite, Pro, and Enterprise are permanent one-time-purchase licenses. New purchases include one year of updates, eligible account and device licensing assistance, and assisted support. Later maintenance renewal is optional and does not disable the purchased application if it expires.

Where is receipt data stored?

Receipt data stays on the local Windows device. Trial jobs are session-only; Lite, Pro, and Enterprise keep local job history.

Can I remove everything later?

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