因网上只有Delphi例子本人在用CB编写时发现有一些例子不能用，

所以一生气就索性查了查资料自己写了，怕网友们在用编程时也遇见此类情况，

就马上传了上来。



void __fastcall TForm1::BitBtn1Click(TObject *Sender)

{

char *ADevice, *ADriver, *APort;

THandle DeviceMode;

PDeviceMode DevMode;

int length,width;

length=1400;

width=2410;//设定自定义纸张的尺寸单位为0.1毫米

ADevice =new char[100];

ADriver =new char[100];

APort =new char[100];

//获取打印机

Printer()->GetPrinter(ADevice, ADriver, APort,DeviceMode);

//获取PDevMode结构

DevMode =(_devicemodeA*) GlobalLock((void *)DeviceMode);

//设定可以修改的值

DevMode->dmFields = DevMode->dmFields|DM_PAPERSIZE;

DevMode->dmFields = DevMode->dmFields|DM_PAPERLENGTH;

DevMode->dmFields = DevMode->dmFields|DM_PAPERWIDTH;

//设定要修改的值

DevMode->dmPaperSize=DMPAPER_USER;//设为自定义纸张

DevMode->dmPaperLength=length;

DevMode->dmPaperWidth=width;



//测试打印

Printer()->BeginDoc();

TextOut(Printer()->Handle, 0, 0, "-----------------",17);

Printer()->NewPage();

TextOut(Printer()->Handle, 0, 0, "++++++++++++++++++",18);

Printer()->NewPage();

Printer()->EndDoc();

}
