// Add custom action buttons in woocommerce order list
add_filter( 'woocommerce_admin_order_actions', 'add_custom_print_actions_buttons', 100, 2 );
function add_custom_print_actions_buttons( $actions, $order ) {
    $opts = get_option('xc_woo_cloud_print_options', array());

    //if (isset($opts['printer']) && $opts['printer'] != "") {
        $domain = 'woocommerce-pdf-invoices-packing-slips';

        $slugs_label_names = array(
            'invoice'       => __('Invoice', $domain ),
            'packing-slip'  => __('Packing Slip', $domain )
        );

        // Set the action button
        foreach ( $slugs_label_names as $slug => $label_name ) {
            $actions[$slug] = array(
                'url'       => wp_nonce_url( admin_url( "admin-ajax.php?action=xc_woo_printer_job&document_type={$slug}&order_id=" . $order->get_id()), 'xc_woo_printer_job'),

尝试以下内容（根据您的问题代码）

// Add your custom action buttons
add_filter( 'woocommerce_admin_order_actions', 'add_custom_print_actions_buttons', 100, 2 );
function add_custom_print_actions_buttons( $actions, $order ) {
    $opts = get_option('xc_woo_cloud_print_options', array());

    if (isset($opts['printer']) && $opts['printer'] != "") {
        $domain = 'woocommerce-pdf-invoices-packing-slips';

        $slugs_label_names = array(
            'invoice'       => __('Invoice', $domain ),
            'packing-slip'  => __('Packing Slip', $domain )
        );

        // Set the action button
        foreach ( $slugs_label_names as $slug => $label_name ) {
            $actions[$slug] = array(
                'url'       => wp_nonce_url( admin_url( "admin-ajax.php?action=xc_woo_printer_job&document_type={$slug}&order_id=" . $order->get_id()), 'xc_woo_printer_job'),
                'name'      => $label_name,
                'action'    => $slug,
            );
        }
    }

    return $actions;
}

// Set Here the WooCommerce icon for your action button
add_action( 'admin_head', 'add_custom_print_actions_buttons_css' );
function add_custom_print_actions_buttons_css() {
    $slug_icons = array(
        'invoice'       => '\f497', // '\e02b',
        'packing-slip'  => '\f491', // '\e028',
    );
    // Added Woocommerce compatibility version
    $class  = version_compare( WC_VERSION, '3.3', '<' ) ? '.view.' : '.wc-action-button-';

    echo '<style>';

    foreach ( $slug_icons as $slug => $icon_code )
        echo $class.$slug.'::after { font-family: dashicons !important; content: "'.$icon_code.'" !important; font-size:1.4em !important; margin-top: -4px !important; }';

    echo '</style>';
}

代码放在活动子主题（或活动主题）的function.php文件中。测试和工作，它也应该适合你。
