自定义纸张打印失败，求高手过来看下

我在"Kyocera TASKalfa 400ci KX"打印机上打印一个自定义大小（200*400）的纸张，但是打印总是以默认纸张大小出纸。网上我也找了很多代码，他们的写法都跟我类似，但还是设定不上。下面是我的源码，求高手帮忙看下：



#include "stdafx.h"

#include <windows.h>

#include <winspool.h>



class ScopeHDC {

	HDC hdc;

public:

	explicit ScopeHDC(HDC hdc) : hdc(hdc) { }

	~ScopeHDC() { DeleteDC(hdc); }

	operator HDC() const { return hdc; }

};

	devMode->dmFields = DM_FORMNAME; 

	wcscpy(devMode->dmFormName,pF1->pName);
