带有spring MVC的JasperReport：在客户端打印报告而不显示它(JasperReport with spring MVC : print report on client side without displaying it)

 我正在开发一个Spring MVC - Angularjs应用程序。 
 我需要打印报告，我选择了JasperReport来做到这一点。  
 在我继续之前，我想知道我是否可以生成报告，然后将其直接打印在客户端计算机上设置的默认打印机（可根据用户更改的打印机） 上 ， 而不在屏幕上显示。 
 我一直在寻找这个特定需求的答案，但找不到任何答案。  
 如果有人知道它....  
 生成报告并打印它的来源：  
HashMap<String, Object> params = new HashMap<String, Object>(); 
params.put("Title", "My Report");

InputStream reportStream = this.getClass().getResourceAsStream(TEMPLATE); 
JasperDesign jd = JRXmlLoader.load(reportStream);
JasperReport jr = JasperCompileManager.compileReport(jd);
JasperPrint jp = JasperFillManager.fillReport(jr, params, datasource.getDataSource());

JasperPrintManager.printReport(jp, false);

I am developping a Spring MVC - Angularjs application.
 I need to print reports, I chose JasperReport to do that.  
Before I move on, I want to know if I can generate a report, then directly print it on the default printer set up on the client computer (printer which can change according to users) without displaying it on screen.
 I have been looking for answers on this specific need, but couldn't find any. 
If anyone knows about it....  
Source to generate report and print it: 
HashMap<String, Object> params = new HashMap<String, Object>(); 
params.put("Title", "My Report");

InputStream reportStream = this.getClass().getResourceAsStream(TEMPLATE); 
JasperDesign jd = JRXmlLoader.load(reportStream);
JasperReport jr = JasperCompileManager.compileReport(jd);
JasperPrint jp = JasperFillManager.fillReport(jr, params, datasource.getDataSource());

JasperPrintManager.printReport(jp, false);

  将导航控制器嵌入到故事板的第一个视图中  
  然后尝试使用此代码： - 
@IBAction func signUpComplete(_ sender: Any) {


if self.signUpEmailField.text == "" || self.signUpPasswordField.text == "" {

    let alert = UIAlertController(title: "Oops!", message: "A valid E-mail and Password are Required", preferredStyle: UIAlertControllerStyle.alert)
    alert.addAction(UIAlertAction(title: "Ok", style: .cancel, handler: nil))
    self.present(alert, animated: true, completion: nil)

}else{

    FIRAuth.auth()?.createUser(withEmail: self.signUpEmailField!.text, password: self.signUpPasswordField!.text, completion: { (user, err) in

        if let ErrorCode = FIRAuthErrorCode(rawValue: err!._code){

            switch ErrorCode {

            case .errorCodeEmailAlreadyInUse : let emailExists = UIAlertController(title: "Oops!", message: "A user with this E-Mail already exists!", preferredStyle: UIAlertControllerStyle.alert)
                                               emailExists.addAction(UIAlertAction(title: "Ok", style: .cancel, handler: nil))
                                               self.present(emailExists, animated: true, completion: nil)

                                               break

            default                      :  break 

            }

        }else{

            let nextView = self.navigationController!.storyboard!.instantiateViewController(withIdentifier: "signUpSucceededSegue")
            self.navigationController!.pushViewController(nextView, animated: true)

        }
    })
  }
}
 
 
 然后以类似的方式更改您的其他代码块。 

 
 Embed a Navigation Controller to the very first view of your storyboard 
 Then Try using this code:-
 @IBAction func signUpComplete(_ sender: Any) {


if self.signUpEmailField.text == "" || self.signUpPasswordField.text == "" {

    let alert = UIAlertController(title: "Oops!", message: "A valid E-mail and Password are Required", preferredStyle: UIAlertControllerStyle.alert)
    alert.addAction(UIAlertAction(title: "Ok", style: .cancel, handler: nil))
    self.present(alert, animated: true, completion: nil)

}else{

    FIRAuth.auth()?.createUser(withEmail: self.signUpEmailField!.text, password: self.signUpPasswordField!.text, completion: { (user, err) in

        if let ErrorCode = FIRAuthErrorCode(rawValue: err!._code){

            switch ErrorCode {

            case .errorCodeEmailAlreadyInUse : let emailExists = UIAlertController(title: "Oops!", message: "A user with this E-Mail already exists!", preferredStyle: UIAlertControllerStyle.alert)
                                               emailExists.addAction(UIAlertAction(title: "Ok", style: .cancel, handler: nil))
                                               self.present(emailExists, animated: true, completion: nil)

                                               break

            default                      :  break 

            }

        }else{

            let nextView = self.navigationController!.storyboard!.instantiateViewController(withIdentifier: "signUpSucceededSegue")
            self.navigationController!.pushViewController(nextView, animated: true)

        }
    })
  }
}
 
 
Then alter your other code-block in the similar fashion.
