你是用流保存进去的吧？再用流的方式读出来，在Image打印控件中显示出来就可以了！
var
Stream:TMemoryStream;
jpgstream: TJpegImage ;
begin
if QryImage.Value<>'' then
begin
Stream:=TMemoryStream.Create ;
jpgstream:= TJPEGImage.Create;
QryImage.SaveToStream(Stream);
Stream.Position := 0;
jpgstream.LoadFromStream(Stream);
QRImage1.Picture.Assign(jpgstream);
Stream.Free;
jpgstream.free;
end;
end;
