I have the following equipment: Linksys Router, wireless laptop with Vista operating system, desktop with Win XP operating system, HP pcs 2410 Photosmart all-in-one (which isconnected todesktop). What must I do to print from wireless laptop to a HP psc 2410 Photosmart all-in-one?

Go to your desktop, goto printers and faxes, right click on the printer, goto sharing and click on share this printer and give it a name like "printer" and click apply and ok. Now ensure that you have network discovery and network list service turned on and running on your vista machine and then goto printers and click on add new printer and go add network printer and in the address of the printer provide \\machinename\printername and click ok to any prompts for install of drivers on any other prompts that UAC might throw up. Your vista machine should now be able to print as long as your desktop is up and running.
