I had the same problem, most people would browse for the printer wirelessly or bluetooth. then would be able to print but yet word or excel opens up slow.
Frist delete the printer you already have setup, also delete any other pritner you dont use anymore.
Use local printer .... Click on... create a new port..... (in the box it must say local port). a window opens up.
Type in the path of the computer and replace the drivers with vista drivers in that list or cd you have. It'll ask you to replace or reinstall the current drivers .. just replace it, even tho it says recommended. Then drivers will reinstall itself then word/excel should work. Any other questions just reply.
