Solution
yes, using your code:
B4X:
Sub POS_onBind()
' You can now use the BDxxx Methods. The Service is connected.
Log($"POS_onBind()"$)
'pos.BDconnectBtPort("00:00:00:00:00","BDconnectBtPort")
pos.BDconnectBtPort("DC:0D:30:06:98:71","BDconnectBtPort")
End Sub

Ok. I´ll try to teach you how you can "translate" the code in the Exampleapp they provided:
In the app you can for example start to print a barcode-test....
This is the code
As MainActivity you can see your activity you are running a instance of my lib.
The "binder" is the one you got in the Event
. Okk you dont GET it... Just the info that the binder is now available.
writeDataByYouself is the same named Method in my library.
Inside the code are two callbacks defined. One for successfull and unsuccefull result, one for handling of the commands. Here i ned to return the comand list to the library behind....
The interesting part is
Here a list of commands are gnerwated and returned to the lib behind... This is what you need to do in b4a.
This is the code you need in b4a for this
After this code the lib send the commands to the printer and it will end in raising either a successful or failed event with the given tag, In this case "Barcode"
The last item added to the list causes a problem here. I needed to extend the lib. Find the new lib attached.
In the app you can for example start to print a barcode-test....
This is the code
B4X:
private void printBarcode(){
MainActivity.binder.writeDataByYouself(new UiExecute() {
@Override
public void onsucess() {
}
@Override
public void onfailed() {
}
}, new ProcessData() {
@Override
public List<byte[]> processDataBeforeSend() {
ArrayList<byte[]> list=new ArrayList<byte[]>();
//first you have to set the width and heigt ,
// you can also use dot or inch as a unit method, specific conversion reference programming manual
list.add(DataForSendToPrinterTSC.sizeBymm(60,30));
//set the gap
list.add(DataForSendToPrinterTSC.gapBymm(0,0));
//clear cach
list.add(DataForSendToPrinterTSC.cls());
//print barcode
list.add(DataForSendToPrinterTSC.barCode(60,50,"128",100,1,0,2,2,"abcdef12345"));
//print
list.add(DataForSendToPrinterTSC.print(1));
return list;
}
});

Maybe, to come back to you initial post, use it like this
B4X:
Dim list As List
list.Initialize
'//default Is gbk,If you don't set the charset
pos.CharsetName = "gbk"
list.Add(pos.sizeBymm(60,30))
list.add(pos.gapBymm(0,0))
'// clear the cache
list.add(pos.cls())
'//barcode command，parama：int x: x print start point；int y:y print start point；
'//string font，text font Type ；int rotation，angle of rotation ；
'//int x_multiplication，Font x directional magnification
'//int y_multiplication,Font y directional magnification
'//string content，print cont
list.Add(pos.text(10, 10, "1", 0, 1, 1,"abc123"))
'//print line,int x;int y;int width，width of the line ;int height,height of the line
list.add(pos.bar(20,40, 200, 3))
'//print barcode
list.add(pos.barCode(60, 50, "128", 100, 1, 0, 2, 2,"abcdef12345"))
list.add(pos.feed(20)) ' Added feed
list.add(pos.cut) ' Added CUT

list.add(pos.print(1))

lol. I did not expect this. Not really...
Ok, i´ll investigate and check the lib.
Can you please try if the method to print a bitmap works? Or does it print the command also?

I rechecked the example project. The 3rd party jar contains three different "Sets of Commands" (all bytearrays).
What i wrapped was the TSC Set.
Then there is a set for Pos80 too (with a lot of new methods like in the TSC one). The Pos80-Set has Commands to switch the printing model.
Hold on; i´m writing a helper for the POS80 Commands too.

In the Pos80 helper you´ll find different methods starting with "select". Check if one of these is able to switch the printing mode (printing model).
Also check method
and try different values...

In the meantime that @DonManfred's printer arrive..or I can make the new library work..
I'd like to go back to the original code and do a try..
Notes:
-Using the code-demo the printer is printing OK,
-Using this App (posprinterdriver) the printer is cutting the paper
How should I send this Chr(29) & Chr(86) & Chr(48) command to the printer?
The right way to send those commands..
Edit: I have the English manual now, attached..

Printer.Close
BTConnection.Disconnect 'disable this if you like
Else
Msgbox("No printer found...","Print error")
