Can you hook a cell phone up to a printer?

That printer must have a wireless connectivity system built-in such as bluetooth or wi-fi.

To print the item you want. You just need to open the item in your cell-phone. And then, in the options menu, select 'print' or 'print via <name>'. You need to do all this keeping the printer on and then following the steps that vary in every phone of different operating systems.
