title: Angular 2+ print manually ngx print
body: <p>I need to print a <code>div</code> using <code>ngx-print</code> in Angular +2, but send it manually, not as button attribute <code>ngxPrint</code></p>
  
  <pre><code>&lt;button printSectionId="print-section" (click)="printProcedure()"&gt;print&lt;/button&gt; 
  
      printProcedure(){    
           /* DO SOME STUFF*/  
          //Print out after validations   
          ngxPrint.print() 
       }
  </code></pre>
