Problems with PrintTitleRows

Hi.

So, i’m create XML Web Service (c#.net) to export some data from MS SQL Server 2000 to excel file.
I use PrintTitleRows property to set title for next pages.
Web Service return byte[] to IExplorer Responce.Write(byte[]) and user can get standart Open/Save dialor: “File Download”.
All work correctly when i choose save button.
But when user click on Open button, start excel application and PrintTitleRows dosen’t work. 2nd page haven’t any title on print preview and print.

Any Suggestion??
Can anybody help me ???
Thanks.
