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. Take my printer off Air Print and reinstall it on the Canon settings (so I can select the greyscale option - which didn't work).This made no difference and now I am getting blank pages when I print, even in colour. If you are able to print a test page, but you cant print from your program, it will usually mean the program that you are printing from has the wrong printer selected or, there are multiple connections for the printer in your printer list and some of the connections are not active. 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).

Canon printer will only print test page
