A method for enabling a printing machine having a customer billing interface to bill the customer for marking jobs having different sheet sizes includes programming different rates for different size sheets into the printing machine. With receipt of a machine enable signal from the customer billing interface, a sheet is fed and the printing machine determines the sheet size. After the printing machine performs a marking operation, the printing machine emits a signal for each sheet marked to the customer billing interface.

Method and apparatus for charging for printing mixed sheet sizes on an electrophotographic printing machine

In a multifunction digital printing apparatus, such as a copier-printer, image data from print jobs are intermingled with image data from copy jobs, such as originating from a digital scanner. Further, scanner-only functions such as electronic filing and sending facsimiles can be performed without need for printing hardware. An auditing device can decrement a user's account on a per-sheet basis regardless of whether a requested job requires the use of the scanner or printing hardware or both.
