A printing system comprises an intermediate transfer member, an image-forming station comprising a print bar disposed over a surface of the ITM, a conveyer for driving rotation of the ITM, a detection system configured to detect foreign matter transported at a detection location upstream of the image-forming station, and a response system operatively coupled to the detection system to respond to the detection of foreign matter by performing at least one collision-prevention action to prevent a potential collision between foreign matter and the print bar.

A printing apparatus that performs printing on a medium while being manually moved relative to the medium, the printing apparatus including a first discharger including a first nozzle row that discharges a first liquid, a second discharger including a second nozzle row that discharges a second liquid and is so provided as to be separate from the first nozzle row in a first direction perpendicular to the first nozzle row, a movement detection section that detects the moving direction of the printing apparatus viewed from the side facing the printing apparatus while the printing apparatus is moved, and an error process section that carries out an error process when printing using both the first and second dischargers is performed and the moving direction detected by the movement detection section deviates from the first direction.

In an example, a method includes extracting a static value and a dynamic value from a computer readable storage device mounted on a consumable that is locked in a printing device. Based at least in part on a comparison of the static value to the dynamic value, it is determined that the consumable should be unlocked to facilitate removal of the consumable from the printing device. A signal is then sent to a drive mechanism with which the consumable is engaged. The signal instructs the drive mechanism to take an action that unlocks the consumable.
