Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
The short answer here is that you cannot, at least not directly.
You have an older/discontinued (and no longer supported, past its service life) 2011 model printer.
It does not support air-print capability.
There are some possible workaround options, but they can be complicated and involved:
You can connect the printer via usb to an apple router
Or you can connect the printer to a pc that is always on, then install a sharing service to it like google cloud print and put the corresponding app on the ipad. This will give limited functionality for printing photos and documents primarily.
Given the age of the printer however, and as it is already past its designed maximum 3 year service life, I would not consider much investment in it practical at this point. It is likely to fail and need to be replaced in the near future anyway, so it may make more sense to simply replace the printer with an appropriate airprint compatible model at this stage.
I can explain more about the above options or recommend replacements for you, if you'd like.
