A couple of solutions
1 If your printer is not Airprint enabled then buy one that is
2 If your printer manufacturer has an 'app' for the iPad get it.
3 If neither of the above is true then check out apps like Print n Share, Print Central etc.

If you have a Mac you can use several apps on the iPad to print to a printer attached to the Airport Extreme as long as the Mac is on and on the same network. It uses the Mac as an intermediary but it is seemless and to the iPad user it as if you are printing directly. Not sure about using a PC.

Since my answer above, I have learned about enabling AirPrint in Mac OS X SL and Lion. By doing that you can print to any printer that is a shared printer from a Mac. Unfortunately I do not have an AirPort Express*, the OP's question, with which to experiment.
*The AirPort Express is the little one.'09 Mac mini, '06 iMac, iPad 2, Mac OS X (10.7), iOS (4.3.4) Mac fanboy since 1984!

Thank you for helpful comments, I've solved this problem: changed my old (?) HP printer to a brand new HP LaserJet P1102w, and (after few confused days) I was able to use this printer on all of my APPLE devices (MBPro and 2 iPads). And it works great.
