小票打印怎么设计？

Question

类似超市的收款后打印的小票，用QReport设计。宽度固定，长度可变。现在没有小票打印机，要开发后交付的时候再配。怎么设置页面？宽度可以了，按纸张的实际宽度。但长度怎么办？怎么保证小票打印完就停止走纸？

Answer 1

小弟见过那种小票的制做方法是:把要打印的内容写到一个文本文件里,最后调用一个批处理文件用Copy 文件到LPT就行了.用的打印机是:Epson的Pos58热敏打印机.

我有一个小票打印的代码.都是写到程序里。你就随便看看吧.写得早了。
procedure TDPrintFrm.SpeedButton1Click(Sender: TObject);
var
   Year,Month,Day:Word;
   DateTime:String;
begin  DecodeDate(now,Year,Month,Day);
  DateTime:=Format('%d-%d-%d',[Year,Month,Day]);

procedure TForm1.ButtonPrintClick(Sender: TObject);
var
  PText:TextFile;
  i:integer;
begin
  Printer.Canvas.Font.Charset:=GB2312_CHARSET;
  AssignPRN(PText);
  Rewrite(PText);
  Printer.Canvas.Font.Name:='黑体';
  Printer.Canvas.Font.Size:=10;
  writeln(Ptext,'POS 票据');
  writeln(Ptext,'');
  writeln(Ptext,'品名  单价   数量   小计');
  For i:=1 to ADODataSetPJ.RecordCount do
    writeln(Ptext,ADODataSetPJ.FieldByName('pm').asString+
    ADODataSetPJ.FieldByName('dj').asString+
    ADODataSetPJ.FieldByName('sl').asString+
    ADODataSetPJ.FieldByName('hj').asString);
  writeln(Ptext,'');
  CloseFile(Ptext);
end;改进一下就可以了
