I recently purchased a printer from HP and successfully set it up to print with my MAC desktop. I was assured of compatibility and also six months' free ink. However, the app I needed to determine when the ink should be sent can only be downloaded on iPhone or iPad. My iPhone is several years old and does not take the app. I spent three hours over two conversations before being told I could not get the app or the free ink. I was transferred four times (wrong transfer extension twice). Each time, I had to go over the same problem, and it was very difficult to get the agents to understand what I was saying and equally difficult for me to understand them.
