IE9 wont print (using high amount of ram), open a new tab and it will print fine (same session)

Hi Guys

(Enterprise Network) 

Im having an Issue where IE9 will be printing off our intranet fine for a while, it starts using a high amount of ram and will not print at all.

I can open another tab on the same session and it will print fine, or close the session and open IE9 agian and it will print fine.

anyone had something like this before ? any advise would be great.

currently ive got 1 user test if running IE9 with addons disabled helps.
