When your phone is connected to the printer's hotspot, you can print photos directly from the photo album, depending on whether your phone has the "Black and White" option. If your phone photo album has this mode, you can print black and white photos. If you are unable to set the "Black & White" mode in your phone's photo gallery, we recommend that you use the Lienne app and select the "Black & White" filter to print your photos in black and white.
