[luv-beginners] wireless printing.

Hello,            I am trying to do wireless printing for the first time with Linux but have not succeeded so far. I have a HP photosmart 5520 printer which may not be working properly using a wireless connection.The printer sends out a wifi signal which I am able to connect to using my computer.A notification pops up saying I have connected to it.I am using Linux Mint 18.I don't know where to go from there.How do I print a test page? I have opened system-configuration-printer but the printer does not show up there like it does with a USB connection.The printer does not print using the USB connection as there is something wrong with the printer,I want to test it with the wirless connection before I throw it out. regards Peter
