have you tried switching the usb priter wire to different usb slots?
also, are you sure your ink cartridges are secured correctly?
best way to check if it is your printer or if its windows/drivers, etc.. is if you have an extra printer laying around the house, try connecting that one..
also, look for your printer's company up on a website, search for the model, see if there are any troubleshooting FAQ's that fall into your catagory.
