Abstract:
1. A method for providing driver-independent, printer-independent page manipulation options in a printing system through a page-independent spool file index, said method comprising: reading a spool data file for a document; creating a Page-Independent Spool File (PISF) index file that is distinct from said spool data file, but based on data in said spool data file, wherein said PISF index file comprises a link to said spool data file, wherein said link identifies a portion of said spool data file required to print an independently-formatted page of said document; manipulating said PISF index file, after creation of said PISF index file, to effect a document page format manipulation option, wherein said document page format manipulation option is selected from the group consisting of page order, page copies, page scaling and page placement, thereby producing a manipulated PISF index file; and using a print processor customized to use said manipulated PISF index file, generating printer-ready data, for a modified document created via said page format manipulation, from portions of said spool data file identified by said manipulated PISF index file.
