Merge Options

You can prepend or append and existing file with the newly created file by creating a string value in the registry at any of the standard registry locations.  If you would like to add an existing PDF file to the beginning of the newly created file, you can create a string value named "PDFPrependFile" and set it to the full path of the existing PDF file.  If you would like to append an existing PDF file to the newly created file, you can create a string value named "PDFAppendFile" and set it to the full path of the existing PDF file.  You can specify both a "PDFPrependFile" and a "PDFAppendFile" at the same time, and both options are only used if the output file name was specified by using "PDFFileName".

For example, if you have an existing PDF file named "file1.pdf" and you would like to create a new PDF file named "file2.pdf" with the contents of "file1.pdf" at the beginning of the new file, you would set "PDFPrependFile" to file1.pdf and "PDFFileName" to "file2.pdf".  Alternatively, if you wanted to the contents of "file1.pdf" to be at the end of the new file, you would set "PDFAppendFile" to "file1.pdf" and "PDFFileName" to "file2.pdf".

By default, the "PDFPrependFile" and "PDFAppendFile" entries are removed from the registry after each PDF file is created and you must add the values each time you print.  If you want to prevent the values from being removed after each document, you can create a DWord value named "persistent" at one of the standard registry locations.
