airport express print server

I would like to use one of my airport express' to print only on my network. My trusty old HP laser printer plugged into the express has worked well before. My current situation has forced me to use other modem/routers for work ect.

Now I do miss the USB port on the express that worked so well as a print server for me and my trusty HP.

I've used the AE's for music. Never as a WiFi extender. I'm thinking as an extender and then add the print ability.

Anyone tried this type senario yet?
