使用TPRINTER
C/C++ code?
void __fastcall TForm1::Button1Click(TObject *Sender)
{
TPrinter *Prntr = Printer();
TRect r = Rect(200,200,Prntr->PageWidth - 200,Prntr->PageHeight- 200);
Prntr->BeginDoc();
for( int i = 0; i < Memo1->Lines->Count; i++)
Prntr->Canvas->TextOut(200,200 + (i *
Prntr->Canvas->TextHeight(Memo1->Lines->Strings[i])),
Memo1->Lines->Strings[i]);
Prntr->Canvas->Brush->Color = clBlack;
Prntr->Canvas->FrameRect(r);
Prntr->EndDoc();
}
