Having been involved with printer software for a number of years, I have always found it frustrating when changing ports, drivers and/or printers. The windows printer wizards always seem very slow and adds extra steps when you just want to do a simple operation. My solution is a windows printer management utility, that can show you installed printers, drivers and ports. The printer manager allows you to add/edit and delete any of these with the minimum of printer wizard usage.
Printer Manager can be found on PrinterUtils here.
