TaperVaper

OK thanks for your quick response.
I have an offtopic last question.
How can I show the ship costs without tax in the modern template?

Perfect now works great.
Finally I added the suffix % city for the file to become so :
$ name-$ number-$ company$ city
but I get to put some separator between company and city .

to complete the invoice template I’ve done I’ve seen things of premium templates that I have liked .
I wonder if it is relatively easy to edit these premium templates.
If so will I buy .
I hope your recommendation.

Greetings and thank you very much for technical support

add_filter( 'wpo_wcpdf_filename', 'wpo_wcpdf_custom_filename', 20, 4 );
function wpo_wcpdf_custom_filename( $filename, $template_type, $order_ids, $context ) {
	global $wpo_wcpdf;
	$count = count($order_ids);

	switch ($template_type) {
		case 'invoice':
			$name = _n( 'Factura_TaperVaper', 'Facturas_TaperVaper', $count, 'wpo_wcpdf' );
			$company = $wpo_wcpdf->export->order->shipping_company;
			$city = $wpo_wcpdf->export->order->shipping_city;
			$number = $wpo_wcpdf->export->get_display_number( $order_ids[0] );
			break;
		case 'proforma':
			$name = _n( 'Proforma_TaperVaper', 'Proformas_TaperVaper', $count, 'wpo_wcpdf' );
			$company = $wpo_wcpdf->export->order->shipping_company;
			$city = $wpo_wcpdf->export->order->shipping_city;
			$number = $wpo_wcpdf->export->order->get_order_number();
			break;
		case 'packing-slip':
			$name = _n( 'Albaran_TaperVaper', 'Albaranes_TaperVaper', $count, 'wpo_wcpdf' );
			$company = $wpo_wcpdf->export->order->shipping_company;
			$city = $wpo_wcpdf->export->order->shipping_city;
			$number = $wpo_wcpdf->export->order->get_order_number();
			break;
		default:
			$name = $template_type;
			$company = $wpo_wcpdf->export->order->shipping_company;
			$city = $wpo_wcpdf->export->order->shipping_city;
			$number = $wpo_wcpdf->export->order->get_order_number();
			break;
	}

	if ( $count == 1 ) {
		$suffix = $number . '-' . $company .  $city;
	} else {
		$suffix = date('Y-m-d'); // 2020-11-11
	}

	$filename = $name . '-' . $suffix . '.pdf';

	return $filename;
}

Right, now works perfectly but with the proforma invoice. And I do not understand why.
Thanks again

The first thank you for the fast answer.
I am a relative novice with these things and can not get the code to work.
I would add to fuction.php my son and no matter if it’s the right thing and neither is where I have to put the name of my template in this case is called TaperVaper .
A greeting and thanks in advance

Hi can I use the billing or shipping company like a suffix in the pdf file name?
Now I use this code to the file name:

add_filter( 'wpo_wcpdf_filename', 'wpo_wcpdf_custom_filename', 10, 4 );
function wpo_wcpdf_custom_filename( $filename, $template_type, $order_ids, $context ) {
	global $wpo_wcpdf;
	$count = count($order_ids);

	switch ($template_type) {
		case 'invoice':
			$name = _n( 'Factura TaperVaper', 'Facturas TaperVaper', $count, 'wpo_wcpdf' );
			$number = $wpo_wcpdf->export->get_display_number( $order_ids[0] );
			break;
		case 'proforma':
			$name = _n( 'Proforma TaperVaper', 'Proformas TaperVaper', $count, 'wpo_wcpdf' );
			$number = $wpo_wcpdf->export->order->get_order_number();
			break;
		case 'packing-slip':
			$name = _n( 'Albaran TaperVaper', 'Albaranes TaperVaper', $count, 'wpo_wcpdf' );
			$number = $wpo_wcpdf->export->order->get_order_number();
			break;
		default:
			$name = $template_type;
			$number = $wpo_wcpdf->export->order->get_order_number();
			break;
	}

	if ( $count == 1 ) {
		$suffix = $number;
	} else {
		$suffix = date('Y-m-d'); // 2020-11-11
	}

	$filename = $name . '-' . $suffix . '.pdf';

	return $filename;
}
