Wireless printing to an HP PSC 1310 Series from Windows 8 using Airport Express

Can someone point me to instructions for setting up wireless printing (to an HP PSC 1315) from Windows 8 using an Airport Express? I have a Dell XPS 14z laptop running Windows 8 on which I've installed Bonjour Print Services and an Airport Express (AE) supporting 802.11n. The laptop successfully uses the AE network to get on the internet, but Bonjour does not display any printers. I also have a Macbook Air that is able to print wirelessly to the HP PSC 1315, so I know it works. The problem appears to be with Bonjour, but I'm not certain. I've tried it with and without the 1315 added as a local printer in the Control Panel. Still no luck.

I had this same setup with a prior Windows XP laptop and an 802.11g AE, but alas can't get back there with the "new/better" technology.

Please help.
