Hello,

The free app offers three free prints per day. You can upgrade to unlimited printing through an in-app purchase. Even if you delete and reinstall the app with a one-time purchase, the app will still run as a paid version.

Upgrading to a paid version will cost 30,000 Korean Won.

This app works with Divesoft's Trimix Analyzer HE/O2 gas analyzer.

The following items are required to run the app: 1. USB Type-C to Type-B printer cable (for connecting the analyzer to your phone)
2. Bluetooth ESC/POS-compatible label printer (The printer specifications must include ESC/POS functionality.)

You can purchase these items separately or purchase them through the in-app link.

Before running the app, turn on the printer and check the paper orientation. Register the device on your smartphone.

When you first launch the app, a pop-up will appear asking for permission. Tap Allow, connect the gas analyzer to your phone, and start the gas analysis.

After confirming that the gas analysis results are changing on the app screen, tap the "Print Label" button. The gas analysis results will be printed at the moment of the change. Free app users do not need to worry, as the gas analysis results will remain constant while the pop-up ad is displayed.

Tapping the "Print" button will open a printer selection pop-up that displays a list of Bluetooth devices. Tap the appropriate Bluetooth printer to begin printing.

You can attach the printed label to cylinders, breathing tubes, etc. for use. Enjoy Diving Have fun!

P.S. Of course, there's no support from Divesoft. It would be nice if there was. This feature wasn't available until pre-release, but now a version with both a printer and this feature has been released. ㅠ.ㅠ

PS2. To all divers using the app, may your future dives be filled with calm waters, clear visibility, and unforgettable diving experiences!
