Conceal pagination when printing - utilizing primeng table

Question

Conceal pagination when printing - utilizing primeng table

In my application, I have a main component called Bill which includes a button for printing:

<button class="btn btn-primary" type="button" (click)="printBill()"> Print </button>

I also have a child component named BillProducts that contains a p-table:

<p-table [value]="products" [loading]="loading" [paginator]="allowPaginator" [rows]="1">

The goal is to hide the paginator and display all products when the user clicks on the print button.

printBill() {
    this.allowPaginator = false;
    window.print();
  }

Unfortunately, what is currently happening is that the paginator gets hidden only after the document has been printed, not beforehand.

Does anyone have any suggestions on how to fix this issue?

Answer №1

One potential solution is to slightly delay the execution of window.print(). This will ensure that it runs after Angular's change detection has updated the view. Here's how you can implement this:

printBill() {
  this.allowPaginator = false;
  setTimeout(() => window.print(), 300);
}

Alternatively, you may not even need the 300ms delay. Simply placing window.print() at the beginning of the event loop queue ensures it will be handled after the current loop is completed:

printBill() {
  this.allowPaginator = false;
  setTimeout(() => window.print());
}
