Can anyone shed some light on a printer sharing issue i am having?

I am trying to setup the printer so i can printer share with a laptop. Everything seems to be ok as far as i can tell. Printer is being shown as "ready" on the laptop when i check the status.

The problem is when trying to print. It doesnt matter what program i am trying to print from it causes the program to stop responding. This happens with Word, notepad and even Firefox when trying to print from hotmail.

Oh and im running Vista and Trend Micro internet security on both the desktop and laptop if that helps.
