</dependency>//Initialization
printer = PosPrinter.getPrinter(activity);
//Subscribe to device events
printer.setDeviceCallbacks(new DeviceCallbacks() {
@Override
public void onConnected() {
// ...
}
@Override
public void onFailure() {
// ...
}
@Override
public void onDisconnected() {
// ...
}
});
//Connect to printer
printer.connect();Library in the automatic mode will request switch bluetooth, if it is not turned on, and start the search for devices. When you restart the application, the application automatically connects to the printer, if it is available.
To create a ticket you must use a generator TicketBuilder class:
Ticket ticket = new TicketBuilder()
.header("PosPrinter")
.divider()
.text("Date: " + DateFormat.format("dd.MM.yyyy", date).toString())
.text("Time: " + DateFormat.format("HH:mm", date).toString())
.text("Ticket No: " + (ticketNumber++))
.divider()
.subHeader("Hot dishes")
//...
.menuLine("— 2 Coffee", "3,00")
.right("Total: 12,50")
.dividerDouble()
.menuLine("Total gift", "3,00")
.menuLine("Total", "128,30")
.dividerDouble()
.stared("THANK YOU")
.build();Call the function ticket.getPreview() you get a string that can be use to debug without using the printer.
Example response ticket.getPreview():
