Changing Print Server Dynamically

Does anybody know a way to change the which print server is used by an NT Workstation ?

I currently have two Servers which have access to the same networked printers. From a workstation, I can connect through either server to the chosen printer.
I need to provide redundancy for the printers.
If I connect a workstation to \\SERVER_A\PRINTER1 and SERVER_A crashes, I would like to re-connect the workstation to \\SERVER_B\PRINTER1 (same device) fairly seamlessly.
I have thought of using an alias - \\PR_SERVER\PRINTER1 and having the DNS resolve PR_SERVER to be SERVER_A or SERVER_B but I think that the name resolving is only done once and the workstation would not detect the new IP address.
Only one server is 'active' at any time and they have the ability to udate the DNS tables when they change from 'passive' to 'active'.
