| 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(); } |
