Dell 1355CNW won't print more than one page. Help?

I recently installed the Dell 1355cnw color laser. I'm running it through my Airport. My iMac sees it just fine The trouble is that it stops printing after one page of every doc. Word. Adobe. Doesn't matter. It prints a page and then beeps as if complete. I've run the Apple updater. I've updated drivers (athough Dell's Mac driver support isn't great). This problem makes the printer virtually useless to me. Ironicially, my Windows based machine (which sees the printer through my iMac works fine), which leads me to conclude it's a driver issue.

Anyone have a solution? I'm about to put my head through a wall.

I'm running 10.6.8.

Thanks.
