By default in IIS, the account used to run ASP.NET applications will lack sufficient privelages to access the network printer.

In order to access the printer you will need to either use impersonation in your code:

WindowsIdentity.Impersonate Method

Or configure IIS to run the application under a user account with the required privileges.

Here is another article which explains different methods of impersonation security:

Edit

If you do not feel confident implementing the user impersonation code yourself, here is a link to a codeproject article: (the code is in c# but could be easily converted to VB.NET or compiled into a separate class library and used in your application)
