[ubuntu] HP Deskjet 3050A All-In-One scanner function "computer not found"

view full story

http://ubuntuforums.org – I have a HP Deskjet 3051A all in one printer. I got it installed wirelessly using cups. Everything works fine when initiated from hplip or terminal. But when I press the scan button on the printer it says "Computer not found. Ensure the HP software has been installed on the computer." I installed HPLIP for Ubuntu 12.04 (the one i have) from HPs website. I think it is a driver or something because i even set it up using the USB connection and it still didn't work. I need all possible problems and how they can be fixed. If there is any other info needed or if you want to help me my ema (Hardware)
