I am trying to use the print.always_print_silent entry to print PDF's. I added a print.printer_Mozilla_Save_to_PDF.print_to_filename entry with a string of file:///Users/Test/ If I append something like Test.pdf to the end of the string a file is created as expected in the expected directory. However, if I do not provide a filename explicitly, it does nothing. Is there a way to use a variable such as the %t variable used in Headers / Footers to name the file dynamically? Otherwise I see no way to save multiple files to the directory in the fashion as it will overwrite the previous file with the explicit name. Thank you for your help!
