Abstract
A printing assembly having a guiding and driving system for moving an article past ink emission nozzles. A detecting device detects the movement of the article through the assembly and based on that detection triggers emission of ink by the nozzles. Compressed air jets are forced toward the article, creating suction due to the Bernoulli effect which effectively maintains the article a set distance from the nozzles.
