Thanks for using Apple Support Communities.
For more information on this, take a look at:
AirPort Utility 6.x: Use a USB printer on your Wi-Fi network
Just make sure you have all the updated version of the drivers.
Best of luck,
I did not find your printer as compatible printers for mac but check for your self http://support.apple.com/kb/HT3669#HP
It most likely will work if you connect the printer to the express via USB and download Bonjour printer service for windows http://support.apple.com/kb/DL999 i would give it a try. It will most likely use some generic drivers but it will print.
