In one embodiment, a method for printing a bar in a bar code includes computing a print resolution for printing the bar using Bar Width, Dot Size and Number of Dots where Bar Width is a desired width of the bar, Dot Size is a nominal dimension of each dot measured in a direction across the width of the bar and Number of Dots is a number of dots to be printed across the width of the bar, and adjusting a spacing between dots based on the computed print resolution.

Printing a bar in a bar code

A system includes a carrier, one or more printheads coupled with the carrier in a defined spatial relation, and alignment information associated with the carrier and identifying the defined spatial relation of one or more printheads.

System with alignment information

A printing system includes an ink reservoir, a support, a fluid conduit and a printhead assembly. The fluid conduit is fluidly coupled to the ink reservoir and includes a first fluid coupler. The printhead assembly includes a body configured to be releasably coupled to the support, a plurality of printheads coupled to the body including a first printhead and a second printhead, and a fluid passage fluidly coupled to both the first printhead and the second printhead. The fluid passage includes a second fluid coupler releasably coupled to the first fluid coupler.

Printing system

Various embodiments include methods and systems for monitoring a production line for non-printing events, and responsive to detecting an event, ascertaining whether an operation can be effected with an inkjet printer stationed along the production line.
