The Mopria Print Service app allows you to connect your Android device to a Mopria-compatible printer via a wireless network. Once connected, you can send, receive, and print any documents, photos, and web pages. The app also allows you to customize the settings for each document, including the number of copies, the type of paper, the page size, and the paper's color. You can also choose to add a cover sheet and/or additional binding.

If you have a compatible printer and you want to print using the Mopria Print Service, you will need to install the printer's driver. You will see an option to install the driver when you connect to the printer for the first time.

If you are using a compatible printer and have the Mopria Print Service preinstalled, you will need to connect to the service first before you can use it. You can do this by opening the Mopria Print Service app and selecting the Mopria icon on the top-right. If you are using a compatible printer that is not preinstalled, you will need to download the driver first before you can use it.

You will be able to customize the settings for each document by opening the document and clicking the settings button on the top-right.
