Re: Problem Printing using IWebBrowser2 from IWAM Account on Server 2003

Thanks for your response Scott,

I think the lack of a default printer sounds reasonable. Also, as you
mentioned that directly call SetDefaultPrinter in your ASP environment ,
I'm thinking whether it is still caused by No UserProfile for the daemon
logon session of the ASP process account? Have you tried call the
LoadUserProfile first before calling the SetDefaultPrinter?

Thanks,

| Steven,
|
| I have determined the problem is that there is no default printer. The
api
| call SetDefaultPrinter fails until the user has logged on with
| control-alt-delete. Try creating a user, do a run as to start notepad.
| Select print. You will not be able to specify a default printer.
|
| Thank you for your help.
