Having set up many HP wireless printers I can say either they go smoothly or can become pain. So how are you installing the printer? Did you use the cd that came with it or did you download the program from the web? Either way first step is the install the software without the printer connected (remove the usb cable as well if it is connected to the computer). During installation the program will ask you to connect the printer via a usb attachment. Once done the install will continue. It will ask you how you want to connect and you will choose wireless. Then it will detect the printer and shortly ask for your WEP or WAP security code. The program will then move on and ask you to remove the usb connection. At this point you should be able to print a test page. If you have done all this and are using win7, look on your network page. If the printer shows as a device you can right click and choose enable.
