    Hello,

    I am attempting to customize the genprint.dll print processor to print extra
    info on the fronts of all pages. The print jobs I am working with start with
    a few simplex pages, then switch to duplex pages. The DEVMODE structure
    changes to reflect this. The genprint source code I have from the 2003 DDK
    does not correctly handle this situation ... an entire job is either simplex
    or duplex to this dll. The WinPrint Print Processor correctly handles this
    situation.

    Currently in genprint, devmode changes for a page are only checked inside
    PrintOneSideForwardEMF(). At this point the entire job has already been set
    as simplex or duplex. Any suggestions on how to correctly print combined
    simplex/duplex print jobs based on genprint?
