Automatically Switch Rolls

By using the roll unit as a roll paper feed device, you can load an upper roll (Roll 1 on printer) and a lower roll (Roll 2 on the roll unit), and print on while automatically changing between Roll 1 and Roll 2 depending on the print job.

For details on how to switch between Roll 1 and Roll 2, see "How to Switch Paper Rolls" (Windows) or "How to Switch Paper Rolls" (macOS).
