Answer 1

You have an array in compact.
You should use <div>{{$dsale[0]->links()}}</div>.
I think you should dont compact an array.
return view('reports.directsalereport',compact('dsale','sumt'));
Edited:
You should pass data to your Pdf view, too, so your method for downloading pdf should look like this.
public function dsalepdf()
{
$dsale=DB::table('directsales')
->join('clients','directsales.client_id','=','clients.id')
->join('products','directsales.product_id','=','products.id')
->select('clients.client_name','clients.addr','directsales.*','products.name')
->where('directsales.client_id','=',$id)
->whereBetween('directsales.issue_date',[$fromdate,$todate])
->distinct()
->paginate(3);
$sumt=DB::table('directsales')
->where('directsales.client_id','=',$id)
->sum('directsales.total');
$pdf=PDF::loadView('reports.directsalereport',['dsale' => $dsale,'sumt'=> $sumt]);
return $pdf->download('dsread.pdf');
}

You may need to delete the vendor folder, then run composer install
