Vista - Printing A Document Selected From A Drop Down List

Hi All

I am trying my hand at printing from a web page for the first time. I
have been asked to print what amounts to many pages of data in
response to a button click. The scenario is as follows.

1. The user will select a Product from a Drop Down List.
2. The user will press the print button
3. Based upon the product selected in the Drop Down List I need to
print data gathered
from 3 different data sources. In addition I need to print at
least 5 different documents
(2 Word Documents, 1 Spreadsheet and 2 pdf documents" to a printer
specified in
another drop down list.

Gathering the data I can do.
I have authority to use the printer using impersonateValidUser
I can stream a text file and put that to the printer using
Graphics.DrawString.

However, what I want to do is simply give the PrintDocument object a
Document
name (as per the example I have tried below) and for the full document
to be printed


PrintDocument _doc = new PrintDocument();
string LPrinterName = @"\\Dun-Server3\" +
ddlPrinter.SelectedItem.Text;
_doc.PrinterSettings.PrinterName = LPrinterName;
...........
_doc.DocumentName = @"\\Server1\Temp\Pdf Documents
\MyPdf1.pdf";
...........
_doc.PrintPage += new
PrintPageEventHandler(_doc_PrintPage);
_doc.Print();


Am I going along the correct lines or is there some other way to do
this.

Thanks in advance for any assistance offered.
