I am pulling my hair out trying to print various objects from a .net
web page
My apologies for cross posting but I need an answer and my previous
post has attracted no interest.

ASP.Net 2.0 using C#

This is a simple web page on our intranet (written as a test) and all
I am trying to do is print a document to a named printer.
If I use a StreamReader then I get an output to the printer. This
prints all the lines in the text file to the printer. However, this
only works for basic text files. I cannot achieve an output for an
Excel spreadsheet, a MS Word document or a pdf document.

If I choose not to use a StreamReader then all I get is a blank sheet
of paper no matter what type of file I try to print.

Can anyone please help as I am getting desperate as I need to create a
complex web based printing application very soon.

Honestly, it depends on what you're attempting to accomplish. If a
