   To increase the length of time before the Web Management Site will time out a   login session, carefully following these instructions:
      1.     Navigate to the   PrintUsage installation directory and open the folder marked “Avalon”
      2.       Using a text editor application, open the file “Web.Config”
      3.     On   line 78, BEFORE the section “<httpHeaders>” paste the following   string:
             
      <sessionState   mode="InProc" cookieless="false" timeout="43200"/>
