You can do this a couple ways.

1)   You can install the ProDOC Paperless Printer software. This will keep the "save as" dialog box from popping up.

2)   Install a an additional ProDOC printer. Name the printer ProDOC for Office.  Set he printer to print to a local port utilizing the path to the "toPrint" folder with a file name of form.prn.  Utilize this printer when printing from MS Office products.
