templates/print-order/print-content.php has a check for whether the item_meta is an array and skips it if true, but some plugins (e.g, Woocommerce Partial Orders Pro) store PHP classes in item meta resulting in a PHP fatal error in those cases.

There are multiple ways to prevent the fatals, but one would be to replace lines 164-166 with:

if ( ! is_string( $value ) ) {
	if ( is_object( $value ) && method_exists( $value, '__toString' ) ) {
		$value = strval( $value );
	} else {
		continue;
	}
}
