I was researching a slightly different issue, and in the course of discovering what and how were things going wrong, I came across this article that is quite neat.
Windows 2000 and Windows Server 2003 provide the ability to install a printer using a command line. This is particularly useful when you add or remove a printer from a group of users using a login script or a scheduled event. You can also modify and delete local printers using Windows 2000. The result is that an administrator can control all aspects of a user’s ability to print by having users run a batch file or logon script.
NOTE: Using this command in a login script or a client-launched batch file requires the client computer to be running Windows 2000 or Windows Server 2003. Because the login script runs on the client computer, a Windows NT 4.0 client is unable to process the command.
**NOTE** This can PUSH the settings down to a specific user.
In addition, these commands can be run from an administrator’s workstation or from a server so that the printers are push-installed to the client computers without having to go to the actual computer.
