<button type="button" id="save-and-print" name="action_create" value="save_and_print">Save and print</button>
<button type="submit" name="action_create" value="save">Save</button>
ReceiveItemsController.php

此代码仅使用
voucher.blade.php$received_items非常感谢任何帮助。
您似乎正在使用两个刀片文件。所以只需将
window.print()receive-items.voucher.blade.php<script>
(function() {
window.print()
})();
</script>
一旦 dom 加载，打印窗口就会打开。
其他信息
您也可以在下面做空您的点赞
if ($request->post('action_create') == 'save_and_print')
return view('receive-items.voucher', ['receive_items' => $receive_items]);
return redirect()->route('receive-items.index');
更新 由于要求打印
index.blade.php将额外的变量传递给index.blade，以便您可以使用打印选项。像下面这样
public function index() {
$allowPrint = true; // Your logic goes here
return view('receive-items.index', ['receive_items' => $receive_items,'allowPrint' => $allowPrint]);
}
index.blade.php
@if($allowPrint)
<script>
(function() {
window.print()
})();
</script>
@endif
