I am learning about PrintManager to print text on paper with bluetooth printer. In Visual Basic 6.0, it is very simple and easy to print text. For example if we want to print "Good morning" the code is like this:

Printer.CurrentX = 0
Printer.CurrentY = 0
Printer.Print "Good morning"
Printer.EndDoc

But when I learn  PrintManager in Android Studio Java, I still don't understand.

This is my code in Android Studio:

PrintManager printManager = (PrintManager) getSystemService(Context.PRINT_SERVICE);

printManager.print("print job name", adapter, null)

The question is where to put the text "Good morning" ?

Would you please help me?

I don't know Java especially on android that well.  

I asked chatGPT this Question:

how do I use the PrintManager object in Java?  Where does the output text belong?

It returned this plus an explanation for the  code.  I'm guessing this line is where the object is told what to print.

Everyone has been kind to me in answering my starting out questions so I thought I'd give it a try.  

import android.app.Activity;
import android.content.Context;
import android.print.PrintManager;
import android.print.PrintDocumentAdapter;
import android.print.PrintJob;
import android.print.PrintAttributes;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.print.PrintDocumentInfo;

public class MyActivity extends Activity {
   // ...

   private void printDocument() {
       // Get a reference to the PrintManager system service
       PrintManager printManager = (PrintManager) getSystemService(Context.PRINT_SERVICE);

       // Provide a name for the print job
       String jobName = "MyPrintJob";

       // Create a WebView and load the content you want to print
       WebView webView = new WebView(this);
       webView.setWebViewClient(new WebViewClient());
       webView.loadData("<p>This is the content to be printed.</p>", "text/html", "UTF-8");

       // Create a PrintDocumentAdapter to handle the printing process
       PrintDocumentAdapter printAdapter = webView.createPrintDocumentAdapter();

       // Start the print job
       PrintJob printJob = printManager.print(jobName, printAdapter, new PrintAttributes.Builder().build());

       // Check if the print job has successfully started
       if (printJob.isStarted()) {
           // Retrieve information about the printed document
           PrintDocumentInfo info = printJob.getInfo();

           // Get the output text of the printed document
           String outputText = info.getName();

           // Do something with the output text
           // ...
       }
   }

   // ...
}

Please edit your post and wrap the code in code tags to give it  formatting.

Thank you Mr. Abel for your answer. I will write your code and add, outputText= "Good morning" and run it after I connect my smart phone with bluetooth printer.
