Remarks:

Imprinters are used to print data on documents at the time of scanning, and may be used for any purpose. Endorsers are more specific in nature, stamping some kind of proof of scanning on the document.

Top/Bottom refer to duplex devices, and indicate if the printer is writing on the top or the bottom of the sheet of paper. Simplex devices use the top settings.

Before/After indicates whether printing occurs before or after the sheet of paper has been scanned.
