Media processing device drive mechanisms for selectable media types

A media processing device, comprising:

• a print head extending across a media path, the print head configured to apply indicia to media;
• a platen roller assembly adjacent to the print head and configured to draw the media from a media supply along the media path travelling between the print head and the platen roller assembly, the platen roller assembly including:
• (i) a first platen roller extending across a first portion of a width of the media path, and
• (ii) a second platen roller coaxial with the first platen roller, and extending across a second portion of the width of the media path;
• and
• a drive assembly coupled with the first and second platen rollers, the drive assembly configured to selectively drive rotation of one or both of the first and second platen rollers,
• wherein the drive assembly includes:
• a first motor coupled with the first platen roller and decoupled from the second platen roller;
• and
• a second motor coupled with the second platen roller and decoupled from the first platen roller;
• wherein the media processing device includes a controller configured to selectively activate either or both of the first and second motors.

• wherein the drive assembly includes:
• a motor;
• and
• a clutch mechanism selectively coupling the motor to (i) the first platen roller in isolation, (ii) the second platen roller in isolation, and (iii) the first and second platen rollers.

A method at a controller of a media processing device, the method comprising:

• detecting a media type corresponding to a media supply installed in the media processing device;
• receiving a print command including a media type parameter;
• selecting, based on the detected media type and the media type parameter, a platen roller assembly configuration for a platen roller assembly configured to draw media from the media supply along a media path, the platen roller assembly including (i) a first platen roller extending across a first portion of a width of the media path, and (ii) a second platen roller coaxial with the first platen roller, and extending across a second portion of the width of the media path;
• and
• activating a drive assembly to selectively drive rotation of one or both of the first and second platen rollers, according to the selected platen roller assembly configuration.
