How to print from my IPad & iPhone to HP LaserJet 1536 MFP

If you have a Mac on the network, try an App like Printopia to see if it will allow the iPhone and iPad to print to your printer.

There is a free trial, so you will know if this will work before you buy.

Printopia - Ecamm Network

you need airprint to print and the hp you mentioned doesnt seem to be in the official list of airprint enabled printers: http://support.apple.com/kb/ht4356

therefore if not using printopia have alook at the print n share app

hope this helps 🙂
