Fix for this issue: download and install Windows 2008 SP2 and Windows Vista SP2.

Running Windows Server 2008/Vista (pre-SP2) and have seen an issue where the wrong user is charged. This also correlates with the wrong user being listed in the Windows print jobs queue.

Windows Server 2008 pre-SP2/Vista has been shown to occasionally identify print jobs from client workstations with the wrong user name. This will result in the wrong user being listed in the Windows print queue. Microsoft has acknowledged this bug (accidentally introduced in a critical update) in the following knowledge base article:

Print jobs may have incorrect owners when you share a printer from a Windows Server 2008-based computer or from a Windows Vista Service Pack 1-based computer

This issue was resolved in Windows Server 2008/Vista Service Pack 2. We recommend that customers affected by this issue either upgrade to SP2 or request the hotfix discussed in the above article and schedule time to apply. The issue is most often seen when a user logs in to a workstation, prints, logs out, then another user logs in and prints. The printing credentials of the original user are used for the next and all subsequent users!
