I have a wireless router and a printer (HP C7280). Using th router I can get on the internet but can't print. Should the settings on the laptop be "use offline" and "share"? Or what should the laptop printer settings be?
Is the printer connecting to the wireless network? If no, you will need to run HP's configuration utility to set it up. You may also need to alter the security settings on your wireless router if HP's is not compatible with your current settings.
Also, make sure you've selected the printer, I had a problem with not doing that which baffled me for far too long.
