推荐答案

试试下面的代码

public  void createWebPagePrint(WebView webView) {
		/*if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) 
            return;*/
	    PrintManager printManager = (PrintManager) getSystemService(Context.PRINT_SERVICE);
	    PrintDocumentAdapter printAdapter = webView.createPrintDocumentAdapter();
	    String jobName = getString(R.string.webapp_name) + " Document";
	    PrintAttributes.Builder builder = new PrintAttributes.Builder();
	    builder.setMediaSize(PrintAttributes.MediaSize.ISO_A5);
	    PrintJob printJob = printManager.print(jobName, printAdapter, builder.build());
	   
	    if(printJob.isCompleted()){
	    	Toast.makeText(getApplicationContext(), R.string.print_complete, Toast.LENGTH_LONG).show();
	    }
	    else if(printJob.isFailed()){
	    	Toast.makeText(getApplicationContext(), R.string.print_failed, Toast.LENGTH_LONG).show();
	    }
	    // Save the job object for later status checking
	}
