I have installed the scan driver from support for my MFP 3310cdw but it doesn't appear to be a twain driver. I need a twain driver for my Paperport software.

Any suggestions?

Update:

 I installed the printer on my desktop after changing the IP (hardwired to network) to DHCP and everything is working fine there. I was going to replace an HP B/W MFP and on the laptop had originally used the same IP setup (manually) as the previous printer. That caused Paperport to choke trying to connect to the scanner. So I've removed everything on the laptop and reinstalled using the DHCP generated IP but not the scanner is still connecting to the old IP address. How do I get the twain driver to switch to the new IP address?
