Rotating Collate and Shift Collate are available only for the PCL 6 printer driver and PostScript 3 printer driver.
Collate
Printed output is assembled as sets in sequential order.
Rotating Collate
Every other print set is rotated by 90 degrees.
When the two paper trays contain the same size paper and same paper type in different orientations, the output result will be always Rotating Collate.
Shift Collate
An optional finisher is required for this function.
As printouts are output, the optional finisher outputs each part so it is shifted away from the next printout and you can see where they are separated.
