Systems and methods are provided for maintaining page face counts that reflect the number of pages with printed image data. In some embodiments, if analysis of rasterized bitmap data indicates that the reverse face of a page contains no data when the printer is printing in duplex mode, then the configuration of the printer may be set to single-sided so that the duplex unit on the printer can be bypassed. If both faces contain image data then the printer is set to duplex mode. In particular, when printing in duplex mode, if a reverse page face is blank and does not contain image data, then the blank page face is not included in the page face count.
