Abstract
A printer produces single and double sided images in correct page order using identically oriented sheets. An imprinting path is provided with mechanisms for transferring an image to one side of the sheet. The printer also has a sheet side reversing path that communicates with the imprinting path, and an output path. The printer includes first and second direction reversing paths that communicate with the imprinting path, the first direction reversing path further communicating with the sheet-side reversing path and the second direction reversing path communicating with the output path. A path selection apparatus is operable, when the printer is to imprint a double-sided image, to direct a sheet initially to the first direction reversing path after an image has been imprinted on one side thereof, and to direct the sheet to a second path after a second image has been imprinted on a second side thereof, whereby the sheet is directed to the output path after the second imprinting operation.
