How to print from my IPAD

Buy an AirPrint capable printer.

See this link --> Use AirPrint to print from your iPhone, iPad, or iPod touch - Apple Support

bear in mind that air print is basic at best. So to print out simple stuff it’s fine, if you need more controls than what pages to print you may want to look for a printer that also has an app with it - for example if you buy a canon printer see if canon also has an app that can give you better control.
