Why is the print css acting up in IE?

I have a print css:

<link rel="stylesheet" href="/css/print.css" type="text/css" media="print" />

on a calendar page it doesn't load correctly in IE (older versions of 8 and back). However, if I go to another calendar page -> 开发者_如何学Cprint preview -> return to the first calendar -> and view again the print.css seems to load fine.

Any known cause for this? or is this just IE being... well... IE?

If I view the page with a hard refresh (ctrl + F5) and "Print Preview" the text size is incorrect and text is hidden. If I reload the same page (F5 only) and view "Print Preview" it works as expected. It seems like a caching issue in IE only.
