2. Thermal Receipt Reprinting Workflow #

Cashiers can reprint customer receipts at any time directly from the archive or order popup:

1. Click the Thermal Print button (pi-print) on the invoice row or inside the details popup.
2. TRAX POS queries the active store printer configuration (IndexedDB ➔ printerSettings):
   • Network Thermal Printer: Transmits direct ESC/POS byte streams to the assigned printer IP (e.g., 192.168.2.96:9100).
   • USB / Serial Printer: Communicates through local hardware endpoints (\\.\COM, \\.\LPT, or POS-80).
   • TRAX Local Print Agent: Streams high-density raster bitmap images via the desktop print daemon (silentImage) without showing web browser dialogs.
3. Once printed, the system updates status_print = true locally in IndexedDB and triggers a background sync to the cloud.

3. Retroactive Fiscal Signing (Sign TSE) #

If a transaction was completed while the fiscal cloud service was temporarily offline:

1. The invoice displays a yellow TSE Not Signed warning tag.
2. Click the Sign TSE button (pi-verified) on the invoice row or inside the popup.
3. The system contacts the Fiskaly cloud service to acquire a valid digital transaction signature.
4. The cryptographic signature, start/stop timestamps, and counter are written to the database, ensuring subsequent reprints contain full fiscal proof.

  • Calculated Tax Amount (MWSt).
