autoit の次のコードに問題があります。

私のシステムで利用可能なすべてのプリンタと、各プリンタでサポートされている現在の用紙名をリストすることを想定しています。

しかし、紙名であると思われる一連の「0」のプリンター名のみを取得しています

#include <Debug.au3>
#include <String.au3>
Const $DC_BINS = 6
Const $DC_BINNAMES = 12
Const $DC_PAPERNAMES = 16
Const $DC_PAPERS = 2
Const $DC_PAPERSIZE = 3
Dim $BinNameList
$objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
$colInstalledPrinters = $objWMIService.ExecQuery ("Select Name, PortName from Win32_Printer")
For $objPrinter In $colInstalledPrinters
    $result = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERS, "str", Chr(0), "long", 0)
    $s_struct = ""
_DebugSetup ($s_struct)
    $s_struct=_StringRepeat("0", $result[0]*64)
    ;$s_struct = StringTrimRight($s_struct, 1)
    $struct = DllStructCreate($s_struct)
    $result2 = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERNAMES, "ptr", DllStructGetPtr($struct), "long", 0)
    _DebugOut ( $objPrinter.Name) 
    For $i = 0 To $result[0]-1
        _DebugOut (DllStructGetData($struct, $i)) 
    Next
    $struct = 0
Next

これをチェックしてください：http://msdn.microsoft.com/en-us/library/aa394363(v=vs.85).aspx

WMI のみを使用する例:

#include <Array.au3>

$objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
$colInstalledPrinters = $objWMIService.ExecQuery ("Select * from Win32_Printer",Default,48)
For $objPrinter In $colInstalledPrinters
    $arr = $objPrinter.PrinterPaperNames
    _ArrayDisplay($arr, $objPrinter.Name)
Next

または、実際の論文名を出力するこれを試してください (SciTE で実行して、ConsoleWrite からの出力を確認できます):

Const $DC_PAPERS = 2
Const $DC_PAPERSIZE = 3
Const $DC_PAPERNAMES = 16

$objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
$colInstalledPrinters = $objWMIService.ExecQuery ("Select Name, PortName from Win32_Printer")

For $objPrinter In $colInstalledPrinters
    $result = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERS, "str", Chr(0), "long", 0)

    $s_struct = ""
    $s_struct2 = ""

    For $i = 1 To $result[0]
        $s_struct = $s_struct & "char[64];"
    Next

    For $i = 1 To $result[0]
        $s_struct2 &= "long x;long y;"
    Next

    $s_struct = StringTrimRight($s_struct, 1)
    $s_struct2 = StringTrimRight($s_struct2, 1)
    $j = 1

    $struct = DllStructCreate($s_struct)
    $pointStruct = DllStructCreate($s_struct2)

    $result2 = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERNAMES, "ptr", DllStructGetPtr($struct), "long", 0)
    $result3 = DllCall("winspool.drv", "long", "DeviceCapabilitiesA", "str", $objPrinter.Name, "str", $objPrinter.PortName, "int", $DC_PAPERSIZE, "ptr", DllStructGetPtr($pointStruct), "long", 0)

    ConsoleWrite($objPrinter.Name & " on Port: " & $objPrinter.PortName & @CRLF)
    For $i = 1 To $result[0]
        ConsoleWrite(DllStructGetData($struct, $i) & " (" & DllStructGetData($pointStruct, $j) & "mm x " & DllStructGetData($pointStruct, $j + 1) & "mm)" & @CRLF)
        $j += 2
    Next

    $struct = 0
    $pointStruct = 0
Next
