Receipt and termal printer

Hi @zorangelev,

Thank you for your message!

Yes, it is definitely possible to optimize the template for printing on an 80mm thermal printer.

You can use the wcdn_head hook to apply custom print styles. Please try adding the following code to your site:

add_action( 'wcdn_head', 'print_paper_resize', 10 );
function print_paper_resize() {
?>
<style>
@media print {
    @page {
        size: 80mm auto;
        margin: 0;
    }

    html, body {
        width: 100%;
        max-width: 80mm;
        margin: 0 auto !important;
        font-size: 8.5pt;
        font-weight: 550;
    }

    table, tr, td {
        page-break-inside: avoid;
    }

    .shipping-address { width: 80% !important; }
    .billing-address { width: 70% !important; margin-bottom: 1em !important; }

    h2, h3 { margin-bottom: 0 !important; }

    th { padding-bottom: 0 !important; padding-left: 0.5em !important; }
    td { padding: 0.35em 0.35em 0 !important; }

    .order-addresses { margin-bottom: 1em !important; }

    .order-info li strong {
        font-weight: 600 !important;
        display: inline !important;
        padding-right: 1.4em !important;
    }

    .order-info,
    .order-branding {
        margin-bottom: 0 !important;
    }

    .product-quantity,
    .total-quantity {
        padding-left: 1.8em !important;
    }

    .includes_tax {
        white-space: nowrap !important;
    }

    .content {
        padding-bottom: 0;
    }
}
</style>
<?php
}
