Existing users are listed in "Administration > Users". The "New" button lets you create a new user account.
In addition to entering the user name and password, you also define in "Type" whether the user will be local or an MDS user. You can only select "MDS" as the type if Prinect Shooter is linked to an MDS server. See MDS.
The "Type" column in the user list displays your setting.
Note: Remember that "User Properties > Enabled" must be enabled to activate the user for Prinect Shooter Printmanager.
