Systems and Methods for Print Accounting
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.
1 . A method for maintaining a count of the number of printed page faces in a print job received by a printer, the method comprising:
analyzing rasterized bitmap data for at least one page to determine if the bitmap data for a reverse page face of the at least one page is blank;
setting a print-mode parameter of the printer to single-sided, if analysis of the bitmap data indicates that the reverse page face of the at least one page is blank;
setting the print-mode parameter of the printer to duplex otherwise;
printing the page according to the bitmapped data and print mode setting; and
updating a page face count to reflect the number of non-blank page faces printed.
2 . The method of claim 1 , wherein updating the page face count to reflect the number of non-blank page faces printed further comprises incrementing the page face count by two when a page is printed in duplex mode.
3 . The method of claim 1 , wherein updating the page face count to reflect the number of non-blank page faces printed further comprises incrementing the page face count by one when a page is printed in single-sided mode.
4 . The method of claim 1 , wherein the reverse page face is blank when it contains no substantive bitmapped data.
5 . A computer-readable memory that contains instructions which, when executed by a processor, perform steps in a method for maintaining a count of the number of printed page faces in a print job received by a printer, the method comprising:
analyzing rasterized bitmap data for at least one page to determine if the bitmap data for a reverse page face of the at least one page is blank;
setting a print-mode parameter of the printer to single-sided, if analysis of the bitmap data indicates that the reverse page face of the at least one page is blank;
setting the print-mode parameter of the printer to duplex otherwise;
printing the page according to the bitmap data and print mode setting; and
updating a page face count to reflect the number of non-blank page faces printed.
6 . The computer-readable memory of claim 5 , wherein updating the page face count to reflect the number of non-blank page faces printed further comprises incrementing the page face count by two when a page is printed in duplex mode.
7 . The computer-readable memory of claim 5 , wherein updating the page face count to reflect the number of non-blank page faces printed further comprises incrementing the page count by one when a page is printed in single-sided mode.
8 . The computer-readable memory of claim 5 , wherein the reverse page face is blank when it contains no substantive bitmapped data.
9 . A computer-readable medium that contains instructions which, when executed by a processor, perform steps in a method for maintaining a count of the number of printed page faces in a print job received by a printer, the method comprising:
analyzing rasterized bitmap data for at least one page to determine if the bitmap data for a reverse page face of the at least one page is blank;
setting a print-mode parameter of the printer to single-sided, if analysis of the bitmap data indicates that the reverse page face of the at least one page is blank;
setting the print-mode parameter of the printer to duplex otherwise;
printing the page according to the bitmapped data and print mode setting; and
updating a page face count to reflect the number of non-blank page faces printed.
10 . The computer-readable medium of claim 9 , wherein updating the page face count to reflect the number of non-blank page faces printed further comprises incrementing the page count by two when a page is printed in duplex mode.
11 . The computer-readable medium of claim 9 , wherein updating the page face count to reflect the number of non-blank page faces printed further comprises incrementing the page count by one when a page is printed in single-sided mode.
12 . The computer-readable medium of claim 9 , wherein the reverse face is blank when it contains no bitmapped data.
