Please let me know how you got on - I have encountered the same issue today with my home/student edition of Word 2010 and an a3 poster. I have tried embedding the images in various ways onto the page, but no luck. I have a canon pro9000, but I am not sure about drivers. While I am here can anyone say how to scale print from word 2010? I have ended up creating an a4 and an a3 version of the same doc...I used to be able to do it fine from my old version of word...? (sorry if that should go in another thread)
