Hi AMY what verison of Internet explorer are you using? Is it fully updated?
Do you have extra tool bars and what not on IE. Have you run anti spyware and checked on hijack this to see if anything slowing it down?
Also what chat history are you printing and why do you need to print it in IE?
Can we help you find a quicker and easier solution?
IE is far from perfect but like mozilla and chrome (both made on the google coampus i belive) it has its good and bad points.
