The irritation of this unexpected time sink when you’re already busy can take it to another level. But, when something goes wrong (like a faulty printer), instead of making your job easier, it adds a whole new problem for you to solve.

Technology is supposed to make the world simpler. When a printer won’t print black, you’re in a real bind. Whether you’re in a rush, need important documents printed quickly, or are running late for a meeting and need paper documents right now.

This is what was in the pane on the right (it won't paste properly I'm afraid):

Any suggestions would be really appreciated. I am really at a loss as to what else to try.

I changed the smaller black ink cartridge (it lights up red when correctly installed so I know it's right). I have 2 black cartridges in my printer and noticed the big one is still full so realised that I must have some settings wrong on my Mac for it not to print from both black cartridges and thought that explained my problem. A few weeks ago it stopped printing the black ink, so I checked the ink levels but they weren't showing as empty. I have a Canon iP7250 printer which, up until recently, printed fine via Air Print from my Mac. I am using a MacBook Air (OS X El Capitan version: 10.11.3).
