Is there a script that will replace my current network printers with printers on a separate print server?

A. Yes, there is. If you use Group Policy to deploy printers, it's easy to move users to other printers by simply updating the deployed printers. However, unless you're using Windows Server 2008, that process can be tricky.

Randy Foster has written a script that parses the client registry and replaces one print server with another. The printer shares must be similarly named on both the old and new print servers. I reproduce Randy's script here, complete with all his comments. Notice the need to replace the cosrv and co-data-01 values on the new print server.

'This script works well in a login script. When ran from a workstation
'it will loop thru all of the printers installed for the current logged on
'user and if they are connected to the old server they will be removed
'and then remaped to the new server. It will also attempt to descover
'which printer is the default printer in order to reset this if it is one
'of the printers that will be moved.

'Note: All of the printers must exist on the new server before this script
' should be run. If not then the printer will simply be removed from
' users profile and the script will not be able to reconnect them.
' "Print Migrator" is a utility that is part of the Windows 2000 and
' Windows 2003 resource kit. This will create all of the printers
' on the new server while maintaining all of their settings including
' print queue security. Keep in mind that for a time you will see
' duplicate printer if you do a search on printers, one advertisec
' from each server.

'We used this method to move just over 100 printers from one server to another
'and then ran this script as a logon script in a group policy. We let it run for
'a few days in order to allow for some users who don't logout every day have a
'chance to run it. All of our users profiles were updated and they didn't even
'know it was happening. We then deleted all of the printers from the old server.

'Note: The script does not run if you are Terminal serviced or SMS remote controling.
