OK, printer was detected by laptop, this then installed the drivers on the laptop, the laptop then checked for upgrades and downloaded and installed the latest firmware, I then proceeded to print from the laptop and scan from the laptop. After this I then connected my desktop to the router using a wireless adapter (previously connected using an ethernet cable), desktop and router now wirelessly connected, retried connecting printer to desktop, still not detected, gave up on desktop, went back to laptop and now the laptop cannot detect the printer. Laptop running windows 7, desktop running windows 8, both connected together via homegroup.
