Change the IP address of a printer without reinstalling driver

I am contemplating changing the IP address subnetting scheme at one of my client’s locations. The problem is that they print to their two main printers at specific IP addresses. It would be so much easier to pull of the change-over, if I could change only the IP address of the printer on everyone’s workstation without having to uninstall and then reinstall the printer driver.

Is this possible?

You open each of the devices's Printer Properties, and update the assigned Network Port. It might be using a WSD port ("by name"), or IP address. Depends on how it was configured.
