To load a URL and print it as a PDF on Android, you can use the WebView and PdfDocument classes provided by the Android SDK. Here is an example code snippet:

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.pdf.PdfDocument;
import android.os.AsyncTask;
import android.print.PrintAttributes;
import android.print.pdf.PrintedPdfDocument;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import java.io.FileOutputStream;
import java.io.IOException;

public class PdfPrinter {
    private Context context;

    public PdfPrinter(Context context) {
        this.context = context;
    }

    public void printUrlAsPdf(String url, String fileName) {
        WebView webView = new WebView(context);
        webView.setWebViewClient(new WebViewClient() {
            public void onPageFinished(WebView view, String url) {
                // When the page finished loading, generate the PDF
                new PdfGenerator().execute(webView);
            }
        });
        webView.loadUrl(url);
    }

    private class PdfGenerator extends AsyncTask<WebView, Void, Void> {
        @Override
        protected Void doInBackground(WebView... webViews) {
            PdfDocument document = new PrintedPdfDocument(context, new PrintAttributes.Builder().build());
            PdfDocument.PageInfo pageInfo = new PdfDocument.PageInfo.Builder(webViews[0].getWidth(), webViews[0].getContentHeight(), 1).create();
            PdfDocument.Page page = document.startPage(pageInfo);
            Canvas canvas = page.getCanvas();
            webViews[0].draw(canvas);
            document.finishPage(page);

            try {
                FileOutputStream outputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
                document.writeTo(outputStream);
                outputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

            document.close();

            return null;
        }
    }
}

You can then use the printUrlAsPdf method of the PdfPrinter class to print the URL as a PDF. The url parameter specifies the URL to load, and the fileName parameter specifies the name of the PDF file to save. For example:

PdfPrinter pdfPrinter = new PdfPrinter(context);
pdfPrinter.printUrlAsPdf("https://www.example.com", "example.pdf");

Note that this code requires the android.permission.WRITE_EXTERNAL_STORAGE permission to save the PDF file.
