We recently had a client who used account tracking on their Konica Minolta. While all the computers were configured to print from the one account they really only used it when photocopying. This created an issue because we couldn’t find a way to deploy the tracking code through group policy so each time a new user logged into a PC they would have to configure the printers authentication.
Using process manager we were able to find the registry key that stores the authentication information. It is contained in
HKEY_CURRENT_USER\Software\KONICA MINOLTA\KONICA MINOLTA C650 Series PCL\FS1\KONICA C650\AccountTrack
If you configure a printer on a PC, export that key then write a login script to import that key on login the account tracking username and password will be setup.
