Hi,
Sorry for the delayed reply.
To reset Internet Explorers settings you do the following:-
1) Open IE
2) Click on the Tools Menu (generally far right, top)
3) Click on 'Internet Options'
4) On the new 'Internet Options' window that appears select the 'Advanced' tab
5) Click the 'Reset' button
6) After resetting you need to close and reopen Internet Explorer
Once you've done this do a 'print preview' before printing to see if that too has garbled output
