Hello-Bonjour,
First, I am new on Ubuntu and happy with it (thank you) ... but:

I installed a HP Photosmart 5520 Print/Scan with HPLIP and can't have all functions.

  1. Print via USB is ok , but Print via Wifi is not : it remains pending (the printer and computer look correctly connected to the wifi box)

  2. Scan to computer is ko : printer tells to ckeck the computer driver and the function is activated. HPLIP shows nothing about scan.

I do not know what I should do to go further.
Thank you in advance
