So slow and everytime I print it says the printer is unavailable. After 5-6 seconds or more it finds the printer and I can press print. Very frustrating and has never improved in 4/5 years that I can see. **** Another year has passed since I wrote that. Nothing had changed and I notice HP never respond to any app reviews on here... I love my printer but not the app. For clarity, my comment relates to printing from my mobile when I press print from my Gallery, or Word etc
