I am using the Macbook Pro along with the HP Photosmart C8180 wireless printer. Everything on the system works fine except HP Photosmart C8180. Mine HP Photosmart C8180 shows offline every time and it doesnít print mine document. I have performed the diagnostics and it has successes but after that also it shows offline. I also not able to print via USB, now I donít what to do. Can anyone suggest on this and so that I can solve mine issue. Please can anyone suggest on this.
