hi sommerpears, welcome to the forums. 

i'm still waiting for the office to get me my upgrade to CS5. i had them upgrade all the other creatives in the department first and i'm the final designer to go.  oh well, that's what happens when you let the women and children go first... there's no lifeboats left!

 

@Rorsdor, when you say there are lines through the artwork, do you mean the colour is "banding" (...the gradients aren't blending, but show as steps of different colour...)?
i haven't heard of a printing issue specific to CS5 (but then again, i haven't been able to run it through it's paces), what type of printer are you outputting to?

...and to minimize the risk of your problem getting buried and not really answered, start a new thread and hopefully you'll get a better answer.
