How can i print from my ipad?

If your iPad has WiFi and the printer is AirPrint capable, yes.

AirPrint is one option... http://support.apple.com/kb/HT4356

If you don't have a printer supported by AirPrint, look for an app for your printer, i.e. search for Canon, Epson, etc.

Note that you need a wireless printer for any of these options.

Another option for printing from iPad AirPrint Activator is installed in OS X, required to have the printer connected to your Mac is on.
