c# - Printing from ASP.NET to a network printer

Question

I need to send documents to a network printer (myservermyprinter). I'm using the System.Printing classes to print, and it works fine when it's from a Windows Service, but from an ASP.NET app, it's only able to print to local printers, not network printers. The error I'm getting is "Printer Name is not valid" This is what I'm using to get the printer name:

public string PrinterName
{
   using (LocalPrintServer server = new LocalPrintServer())
   return server.GetPrintQueue(@"\myservermyprinter");
}

What are my options here? Is this a permissions problem?

Answer 1

By default, an ASP.NET application runs on a special account with limited rights. Just enough to serve webpages, nothing more. So you'll have to configure the ASPNET user.

By contrast Windows services usually run under local System account (with high privileges)
