Printing a word document[Resolved]

I wanted to print a word document on the server from my asp.net web application. I am getting an error saying "There is insufficient memory. Save the document now" Here is the code where I am seeing the error:

Code:

---

Word.Document oWordDoc = oWordApp.Documents.Open(ref fileName, ref missing, ref readOnly, ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible, ref missing, ref missing, ref missing);

I have looked at other web sites but have not found any thing that can fixed it. I have also looked into DCOM for word. Any help is appreciated.

I got this fixed. Here is what I did:
in the web.config file I added this line

Code:

---

<identity impersonate="true"  userName="computername\username" password="password"/>
