Hello. I'm brand new to this forum, and Mac's as a whole. I'm trying to connect our new MacBook Pro to a HP Photosmart C4680 printer through a wireless network that we purchased yesterday. Both the MacBook and printer were purchased through at the Apple store. Here is our setup: HP printer is shared, but is connected via USB to a Dell desktop. I have successfully been able to print from my Dell laptop through our home's wireless network. Both the Dell desktop and laptops are on Vista. I'm managed to figure out how to add a printer, but I'm at a loss for where I should be seeing the HP as an option to add. I've tried using the IP address of the desktop the HP is connected to, but it doesn't come up. I'd like to know if there is a main place to add a printer on a Mac. I added it by opening Keynote, then attempting to print a doc, then adding the printer. I've managed to add two "ghost" printers and I'd like to remove them because what I did obviously isn't working. Also, I've already loaded the drivers and software for the HP directly onto the MacBook. I did this before trying to print wirelessly. I was able to print if the HP was connected to the MacBook via the USB cable. I appreciate your help to the new guy!
