Snapshot stores the Laserfiche user name and password in the registry if the user chooses to save their credentials. Snapshot settings are stored in the HKCU\Software\Laserfiche\Snapshot8\Profile\CurrentUser key for local printing mode, and the HKLM\Software\Laserfiche\Snapshot8\Profile\SharedPrinter key in shared printer mode. The user name is stored in a REG_SZ value named Username and the password is stored in a REG_BINARY valued named EncryptedPassword.
The data in the EncryptedPassword value is encrypted with an encryption key that varies from machine to machine, so for a mobile user with a roaming profile, the password may not decrypt properly. There is no work-around at the current time.
