The easiest way to do this requires a USB memory device, often known as a "thumb drive". Bring up Anzio Lite or AnzioWin on a PC where it works properly. Insert the thumb drive in a USB port on that PC, and note its drive letter. In Anzio, go to the File menu, then click on "Save settings as" (or "Save defaults as"). In the File Save dialog that pops up, navigate to the thumb drive, and save it there with a ".DEF" file extension.
In the "tray notification area" in the lower right part of the Windows screen, find and use the item to "safely remove" the thumb drive. After Windows gives its OK, remove the thumb drive.
Go to the new PC (or the one having problems). Insert the thumb drive. Bring up Anzio Lite or AnzioWin. Click on the File menu, then "Import settings". Navigate to the thumb drive, find the settings file, and click "Open". Anzio will read those settings into memory, and prompt you to restart Anzio. Say "Yes". You'll be prompted to save your settings on the hard disk of the PC -- do so. That should take care of it, although you may want to check your Printer Setup settings.
(If your File menu doesn't contain "Import settings", you are probably due for an update to Anzio.)
