I also have that problem, my computer is , Windows 7 Home Premium 64-bit SP1, and has a wireless router for a HP Color Laserjet 2840 AIO Printer, my laptop is second hand and it came with no CD's, so I've tried to download everthing I need, but I may have missed something. Thank you very much, for any help you can give me on this matter.
Thanks again,
Stephen Case
