pdftron.PDF.Print.StartPrintJob modifying margins

Our PDF documents are currently created from reports, most of which have a margin of 0.25 inches.

We have the Print.StartPrintJob working relatively well; however, we cannot figure out how to get it to print with actual margins of the PDF. What we are noticing is the left and bottom margins appear to be 0.5 inches, which is resulting in bottom and right side of the PDF pages having text that is cut off.

We can set the mode's scale type to get it to fit in the printed page; however, this is modifying the appearance of the PDF document.

Is there a way to get it to print to the entire corner of the page and not have the 0.5 inch margin at the left and bottom?
