when debugging, your machine acts like the server & the client machines at the same time, that's why your code works. But when you deploy your website to another server machine, then your asp.net code will run there NOT on the client machine.

Now, the question... Do you want to get a list of the installed printers at the client machine? If yes, for what purpose?

Refer - How to get client side printer list in ASP.NET?[^].

Quote:
A Web application does not have access to client systems, for a good reason. Imagine for a second that it was possible. Would any reasonable user like that some unknown site could discover printers or other equipment? This even sounds scary.

To get the printer installed at the client from an ASP.NET webpage you need to use some client tech like Flash or Silverlight or Java Applets or something else. One possible solution could be developing something like this http://goo.gl/eFSPw where the report is exported to PDF for printing purposes. You could export your reports to PDF, merge all of them in order into 1 single PDF file (using PDFSharp) and embed some javascript print code as stated here http://www.vo1dmain.info/pdfsharp-howto-inject-javascript-into-pdf-autoprinting-functionality again using PDFSharp
