Linksys E3000-2nd Router - How To Print Block Websites

I have a home network that consists of two routers. First I have my cable modem that is connected to an Apple Airport Extreme Base Station. I tend to use that as the 'n' network for my computers so any devices using n networking connect to that.I then have a cable that goes from my Apple Airport Extreme Base Station to a Linksys E3000 router. I tend to use that as my g router and connect many devices that only have g wi-fi to it.Here is the problem:Because of a couple children that have iPod Touches and Macbooks I like to have them connect to the E3000 since it has great website blocking. I wish the Apple Base Station had website blocking but as far as I see it doesn't. Also, this website blocking has worked great since I installed the router but here is the problem. They frequently have to print items and they're unable to print since it won't find the printer.

The printer that I have is connected by Ethernet cable to the Apple Base Station It appears I have two ways of connecting the E3000 router to my Base Station. The way I currently have it connected is the E3000 is connected to the Apple router through the Internet port on the back. By doing this I get full internet and website blocking but I am unable to print through it. Yet if I connect it to the Apple router through one of it's numbered (1-4) ports, I still get internet, I'm able to print, but yet the website blocking does not work.Since the Apple base station doesn't have website blocking as far as I know the only way I can think of getting around this is to replace my Apple Base Station with another E3000 but I don't want to do this unless I have to.
