    摘要: An electrographic printer has an intermediate medium for simultaneously printing a first web section of an endless medium and a second web section arranged next to and at a distance from the first web section. Both web sections are drawn along a path past the intermediate medium by a transport system. During the printing process, a tensioning device biases the first and second web sections against the intermediate medium. A web-tensioning unit located downstream relative to the direction of transport of the transport device, applies a traction force to the web sections in the direction of travel. In addition, a first compensation device and a second compensation device separated from the first compensation device are provided between the transport device and tensioning device. The compensation devices bias the first or second web sections as appropriate, against the direction of transport during the printing process.
