How to use

Install the printer on a stable counter or integrate it into a kiosk enclosure. Load thermal paper (58 mm or 80 mm) following the top-loading mechanism and close the cover; the cover-open sensor will confirm correct placement. Connect a tablet or POS device via the USB-C port to enable direct printing and charging, or use Ethernet for networked setups. Configure CloudPRNT Next and any required drivers or web-app settings according to your POS or ordering platform documentation. Use the paper near-end sensor to monitor roll status and replace rolls before they run out to avoid interrupted receipts.

Recommendations

For reliable performance, use manufacturer-recommended thermal paper of the correct width and thickness, keep the printer in environments protected from direct exposure to heavy splashes, and ensure firmware and CloudPRNT settings are kept up to date to maintain compatibility with web-based ordering systems.
