single signal on Arduino. rectangular. DTG printer

Helloy world/

how to create a signal on urduino. rectangular of different durations are not cyclical when you press a button once, for example. on delay I got something, but it is necessary millis how many did not try I can not understand the algorithm, it can somehow be done in a special way.

const int button2Pin = 3;
const int led2Pin = 13;
const int led1Pin = 12;
  
unsigned long led2OnTime;
bool led2On;
bool led1On;
  
void setup() {
  
  pinMode(led2Pin, OUTPUT);
  pinMode(led1Pin, OUTPUT);




  pinMode(button2Pin, INPUT);
  led2On = false;
  led1On = false;
}
  
void loop(){
  
  
  if (digitalRead(button2Pin) == HIGH) {     
    digitalWrite(led2Pin, HIGH);
    digitalWrite(led1Pin, LOW);
    led2On = true;
    led1On = true;
    led2OnTime = millis();
  }
    
  if(led2On) 
    if(millis() - led2OnTime >= 800) {
      digitalWrite(led2Pin, LOW);
      led2On = false;
    }
  if(led1On)
    if(millis() - led2OnTime >= 200) {
      digitalWrite(led1Pin, HIGH);

      digitalWrite(led1Pin, LOW);
