Configure the media sizes
Note:
You cannot disable media sizes that are currently loaded on the printer.
Note:
When you load a media roll the printer automatically detects the roll width. If the detected
roll width is not a standard width, the printer selects the next smaller roll width that is
supported by the printer.
Note:
When you load a media roll with a size that was not yet enabled in the media series, the
system automatically adds the new media size to the custom media series.
