You can do this with CSS:

.invoice td.header img { display: none !important; }

Hello!

Thank you for your reply!

I have managed to get this code using the guidelines on the link with your CSS code & i got this.

add_action( 'wpo_wcpdf_custom_styles', 'wpo_wcpdf_custom_styles', 10, 2 );
function wpo_wcpdf_custom_styles ( $document_type, $document ) {
    ?>
.invoice td.header img { display: none !important; }
}
    <?php
}

Could please let me know if my code is correct?

Looking forward to your reply!

Sincerely,

There’s one accolade too many in there, please try this:

add_action( 'wpo_wcpdf_custom_styles', 'wpo_wcpdf_custom_styles', 10, 2 );
function wpo_wcpdf_custom_styles ( $document_type, $document ) {
    ?>
    .invoice td.header img { display: none !important; }
