Claims12
A printing system comprising:
- a print engine for printing on a substrate in a print zone;
- a drum positioned in proximity to the print zone, the drum supported by a plurality of support rollers in contact with an inner surface of the drum, wherein the print engine is for applying printing fluid in the print zone to a portion of the substrate positioned on the drum.
A printing system comprising:
- a print engine for printing on a substrate in a print zone;
- a drum positioned in proximity to the print zone, the drum supported by a plurality of support rollers in contact with an inner surface of the drum, wherein one of the support rollers is powered to impart rotational motion to the drum.
A printing system comprising:
- a print engine for printing on a substrate in a print zone;
- a drum positioned in proximity to the print zone, the drum supported by a plurality of support rollers in contact with an inner surface of the drum;
- and
- a powered wind roller onto which the substrate is wound after a printing operation, such that the drum is driven indirectly by the substrate in contact with the drum.
