High-speed printer and the uses of such a printer

摘要

The present invention relates to a printer with a single printing motor and a single non-contact heating element characterized in that it includes a printing width and a paper path width greater than that of a double web width between 18.5'' (46.99 cm) and 20.5'' (52.07 cm), and selective control of the writing heads. The writing heads are controlled either in order to use them in a single group to print a centered double-width web, or to use them in two groups of heads to concomitantly print two single-width webs separated by a margin. Both groups of heads or each group of heads can be supplied with one color of ink.
