Impersonation and Printing server-side

[joerage]

I use impersonation to get the printers installed on the web server.

What I have found out is that the impersonated user MUST be logged on
the web server so that a client browser sees the list of printers
correctly.

I would like to know if my conclusion is correct and if there is a way
to resolve that.

My goal is that my web application gets a drop down of the printers
installed on the web server. Then using PrintDocument.Print() sends a
document to the printer.

Any ideas would be welcome.

I suspect this is related to the fact that when you impersonate a user,
their profile isn't loaded. Some (all?) printers are associated with
users rather than the machine. If you need the full profile available,
welcome to a whole world of P/Invoke.

For starters, check whether a call to LoadUserProfile() helps you?
