4.2 Network Connectivity

Printing functionality is typically managed through your chosen Point-of-Sale (POS) application. Once configured within the app, select the print option to generate receipts. The integrated thermal printer operates at 90mm/s.
4.4 Scanning Barcodes
The device's camera can scan 1D, 2D, and QR barcodes. Open a compatible scanning application or a POS app with scanning features, then position the barcode within the camera's view for recognition. Note that 1D barcode scanning may be less robust than 2D code scanning.
