Right. My Wireless LAN Adapter is USB. So is my printer. Whenever I try to print something from the internet (such as sheet music with Sibelius Scorch, different to simply clicking File-Print I can do that but need to press print button to get all sheet music). I have a problem, because I can't use my printer and Wireless Adapter at the same time, I think it overloads the USB or something. How can I fix this?
