Abstract
An ink jet printing head, particularly intended for printing large characters, includes at least two modulation bodies having respective nozzles fitted with a device for adjusting each of the jets generated by the nozzles. A single module for recovering the ink with only one return line is incorporated in the head. The casing of the head receives, on its face, a support for a cover and, optionally, a second umbilical cover. For printing bar codes, the head provides a cascade sequencing of printed rasters with an increasing order of sequencing of droplets due to a charge voltage. The head is oriented to compensate for the inclination of the raster on the support.
