N_UP Partitions
Some printers allow the physical sheet of paper to be divided into equal-sized partitions. For two or three partitions, each sheet is divided along one or two lines equally spaced along the longer side of the sheet. The printer positions a logical page of print data in each partition. This enables printing multiple logical pages with different formats and modifications on a single sheet of paper.
The size and arrangement of the partitions on the sheet depends on the number of partitions and the shape and size of the paper. For two or three partitions, each sheet is divided at two or three points equally spaced along the longer side of the sheet. For four partitions, each sheet is equally divided both vertically and horizontally. See N_UP Printing for more information.
