}
根据以上作适当的修改，应该合用。

还要用画布编写自己的打印程序：
2、打印发货单（小纸条）主函数：
const int RecordsPerPage=8;
void __fastcall TfrmBusiness::PrintByCanvas(AnsiString TabTitle,AnsiString OtherSide,TADOTable *Mymaster,TADOTable *Mydetail)
{
int rc=Mydetail->RecordCount;
int lastpg=Ceil(rc/(RecordsPerPage*1.0));
bool needsnewpg=false;
// Initialize print job
Mydetail->First();//Must have this sentence.
//Printer()->Refresh();
Printer()->BeginDoc();
Printer()->Title = TabTitle;
for (int y=0; y<lastpg; y++) // for each page
{
if (needsnewpg) // page 1 does not need a page break
Printer()->NewPage();
PrintPage(y,lastpg,TabTitle,OtherSide,Mymaster,Mydetail); // print the page
needsnewpg = true; // subsequent pages need page breaks
}
Printer()->EndDoc();
Success("打印完毕。");
}
3、打印自定义纸张的函数

页式打印就是这样。下面3个函数可以解决问题：
1、设置打印机使其可以打印自定义纸张
void __fastcall TfrmSetPrn::btViewSetClick(TObject *Sender)
{
char MyDevice[50];
char MyDriver[50];
char MyPort[50];

THandle MyDeviceMode;
TDevMode *pDeviceMode;
//PrintDialog1->Execute();
// Printer()->GetPrinter(
Printer()->GetPrinter(MyDevice,MyDriver,MyPort,MyDeviceMode);
Memo1->Clear();
Memo1->Lines->Add("设备："+AnsiString(MyDevice));
Memo1->Lines->Add("驱动程序："+AnsiString(MyDriver));
Memo1->Lines->Add("端口："+AnsiString(MyPort));
Memo1->Lines->Add("设备句柄号："+AnsiString(MyDeviceMode));
pDeviceMode=(TDevMode *)GlobalLock((void *)MyDeviceMode);
//char *tmp=pDeviceMode->dmDeviceName;
//Memo1->Lines->Add(AnsiString(((char *)pDeviceMode->dmDeviceName)));
Memo1->Lines->Add("版本号:"+AnsiString(pDeviceMode->dmSpecVersion));// WORD dmSpecVersion版本号;
Memo1->Lines->Add("驱动版本号"+AnsiString(pDeviceMode->dmDriverVersion));//WORD dmDriverVersion驱动版本号;
//Memo1->Lines->Add(AnsiString( WORD dmSize设备模式DEVMODE信息占用空间;
//Memo1->Lines->Add(AnsiString( WORD dmDriverExtra其他信息占用空间;
//Memo1->Lines->Add("域:"+AnsiString(pDeviceMode->dmFields));// DWORD dmFields
Memo1->Lines->Add(AnsiString::StringOfChar('-',Memo1->Width/10));
Memo1->Lines->Add("打印方向："+AnsiString(pOrn[pDeviceMode->dmOrientation-1]));// short dmOrientation;
Memo1->Lines->Add("纸型:"+AnsiString(ppage[pDeviceMode->dmPaperSize])); //short dmPaperSize;
Memo1->Lines->Add("纸长:"+AnsiString(pDeviceMode->dmPaperLength));// short dmPaperLength;
Memo1->Lines->Add("纸宽:"+AnsiString(pDeviceMode->dmPaperWidth));// short dmPaperWidth;
Memo1->Lines->Add("缩放率"+AnsiString(pDeviceMode->dmScale));// short dmScale;
//Memo1->Lines->Add(AnsiString( short dmCopies;
//Memo1->Lines->Add(AnsiString( short dmDefaultSource;
if(pDeviceMode->dmPrintQuality<4)
Memo1->Lines->Add("打印品质:"+AnsiString(pqlty[pDeviceMode->dmPrintQuality]) );// short dmPrintQuality;
Memo1->Lines->Add("x分辨率:"+AnsiString(pDeviceMode->dmPrintQuality) );// short dmPrintQuality;
//Memo1->Lines->Add(AnsiString( short dmColor;
//Memo1->Lines->Add(AnsiString( short dmDuplex;
Memo1->Lines->Add("y分辨率:"+AnsiString(pDeviceMode->dmYResolution));// short dmYResolution;
//Memo1->Lines->Add(AnsiString( short dmTTOption;
//Memo1->Lines->Add(AnsiString( short dmCollate;
//Memo1->Lines->Add(AnsiString( BCHAR dmFormName[CCHFORMNAME];
//Memo1->Lines->Add(AnsiString( WORD dmLogPixels;
//Memo1->Lines->Add(AnsiString( DWORD dmBitsPerPel;
Memo1->Lines->Add(AnsiString::StringOfChar('-',Memo1->Width/10));
Memo1->Lines->Add("纸宽点数:"+AnsiString(pDeviceMode->dmPelsWidth));// DWORD dmPelsWidth;
Memo1->Lines->Add("纸高点数:"+AnsiString(pDeviceMode->dmPelsHeight));// DWORD dmPelsHeight;
//Memo1->Lines->Add(AnsiString( DWORD dmDisplayFlags;
//Memo1->Lines->Add(AnsiString( DWORD dmDisplayFrequency;

GlobalUnlock((void *)MyDeviceMode);
frmBusiness->IsPreview=false;


}

系统打印机的纸张选择应正确设置，最好新建一自定义纸张，将默认纸张为自定义纸张，
该方法未试，不能确定是否会解决问题
