Missing Printer table "title" in child array.

Answer 1

You can simply run
$resources = Resource::with('orders.printer')->paginate(6);
an you will get all the data you need
[
{
"id": 2,
"title": "user 2",
"orders": [
{
"id": 190,
"resource_id": "2",
"printer_id": 2,
"printer" : {
"id" : 2,
"title" : "user 2"
}
},
{
"id": 193,
"resource_id": "2",
"printer_id": 3,
"printer" : {
"id" : 3,
"title" : "user 3"
}
}
]
}
]
Edit
You need the printer() relation declared in the model Order::class
class Order extends Model {
public function printer() {
return $this->belongsTo(Printer::class);
}
}
