Previously, worksheet printing in IE didn't really work on textivate.
It's fixed now :0)
You now get the activity opening in a new screen, with a print button.
You can click the print button to print the content, OR right-click the page and choose "Print preview" if you want to change the margins, zoom etc and remove dates, headers, footers etc.
It works great on the versions of IE that I've tried it on.
The print preview feature with the zoom etc means you can get much more precise worksheets than you can even with Google Chrome!
