HP Deskjet printer buying guide

This is my printer that i bought on July 18, 2010. And Its a good printer after using it for a while. And the print quality is pretty nice. Its a 3-in-1 printer so it has Copy, Print, Scan. You can choose from Black or Color for Scan or Copy. Features: + Light Indicators to represent (No Paper) (Low Ink for Color and Black) + Ability to check the status of each ink under the HP Solution Center + Copy, Scan, and Print

My HP Solution Center under Other Devices lists 2 devices both named $FriendlyName$ (including the $ marks). Clicking on various Settings when either of these devices is selected indicates they are not set up. A 3rd device, my HP Printer also is listed and works OK. Why are these 2 $FriendlyName$ Other Devices listed here and how do I remove them?
They do not show up on the Control Panel/Printers screen for either of the 2 computers on my home network; one XP, one VISTA. My printer is connected directly to router via LAN cable. HP Solution Center on VISTA machine now lists 2 $Friendlyname$ devices while HP Solution Center on XP machine lists only 1 $FriendlyName$ device. HP HelpDesk told me that since my printer works when selected there is no HP problem. Yet, the only place I see $FriendlyName$ devices is in HP Solution Center and they don’t work when selected. Could these somehow be trying to identify the Scan or Copy or Flash Drive functions of the HP PhotoSmart C7250?
