Change the title "Invoice" on prestashop invoice

[Massimo333]

How can I change the title "invoices"  in invoices generated by prestashop for orders placed by customers?

Hi, you can modify it in ROOT/pdf/header.tpl

I try to see ROOT/pdf/header.tpl (see below), but on this fil I find only a generic "{$title|escape:'html':'UTF-8'}".

How can I change ROOT/pdf/header.tpl fil to have "MY-CUSTOM-TITLE" on invoice?

 

<table style="width: 100%">
<tr>
	<td style="width: 50%">
		{if $logo_path}
			<img src="{$logo_path}" style="width:{$width_logo}px; height:{$height_logo}px;" />
		{/if}
	</td>
	<td style="width: 50%; text-align: right;">
		<table style="width: 100%">
			<tr>
				<td style="font-weight: bold; font-size: 14pt; color: #444; width: 100%;">{if isset($header)}{$header|escape:'html':'UTF-8'|upper}{/if}</td>
			</tr>
			<tr>
				<td style="font-size: 14pt; color: #9E9F9E">{$date|escape:'html':'UTF-8'}</td>
			</tr>
			<tr>
				<td style="font-size: 14pt; color: #9E9F9E">{$title|escape:'html':'UTF-8'}</td>
			</tr>
		</table>
	</td>
</tr>
