02.2- PrintAgent Desktop Daemon & Silent Printing Setup #
Standard web browsers display a print confirmation preview dialog every time you print. To achieve true silent, instant (0.1s) POS printing, TRAX provides a dedicated Windows background service called TRAX PrintAgent.
1. Why Use TRAX PrintAgent? #
- Zero-Click Silent Printing: Eliminates browser print dialogs; receipts print the instant you click “Pay”.
- Direct USB & Serial Hardware Control: Communicates directly with local USB printer ports (
USB001,COM1) that browsers cannot natively access. - Cash Drawer Pulse Control: Directly triggers the RJ11 cash drawer kick-out signal.
2. Installation & Quick Setup #
- Download the PrintAgent Installer package from your store management portal (
PrintAgent/daemon). - Run the installer as Administrator on your Windows POS terminal.
- The setup registers a lightweight background service (
localprintagentservice.exe) that starts automatically with Windows. - Open the PrintAgent status window from your system tray to verify:
- Service Status:
Active & Running(indicated by a bright green badge). - Listening Port:
8080(or configured custom port). - Web App Link: Shows
Connected to TRAX POS Web App.
- Service Status:

3. Connecting TRAX POS to PrintAgent #
- Inside your TRAX POS browser window, go to Settings ➔ Printers.
- Enable the Use Local PrintAgent Service toggle.
- Leave the service URL as
http://localhost:8080(or enter the IP of the PC sharing the printer if printing over the local network). - Select the target physical printer from the dropdown menu populated by the service (e.g.,
EPSON TM-T88VI (USB001)). - Click Test Print via Agent. A silent test receipt will print instantaneously!
4. Service Maintenance & Debugging #
- Status shows Disconnected: Verify that your local antivirus or Windows Firewall is not blocking local port
8080. - Restarting the Service: In Windows, open
services.msc, locate TRAX Local PrintAgent Service, and click Restart. - Log Inspection: The live log console within the desktop window tracks every incoming print job ID and raw ESC/POS dispatch status.
