For a start, you can print the "Quick start" file inside PrintCentral.

PrintCentral will print directly to most printer models without extra software, but we recommend you install the free WePrint printer sharing software if you have any problems connecting to your printer, or if your printer has a USB connection.
Install WePrint on your Mac or PC from here https://esz.nz/wp

1. Open the Print window (View) inside PrintCentral.
2. If you are not taken to the choose "Printers" screen automatically, tap on the "Choose" button
3. Your network will be searched for available printers. Tap to select your printer
4. If you did not select the green WePrint printer, you can use the "Setup" screen to choose the best printer option for your printer.
5. Tap on "Test" beside each option to test it. Tap on "More" to select more options eg. Canon, Epson, HP, Brother. If you printer prints a lot of blank pages, pull the paper tray out and restart your printer.
