When a physical printer has hard margins, it will not print on the areas covered by those margins. It will print only in the remaining area.

When you print using these printers, PDFOne's printer component will print after offsetting these hard margins on all four edges of the paper. This may cause the print content to be shrunk on all sides or some content along the right and bottom margins to be clipped.

To avoid this problem, you need to set PDFPrinter.OffsetHardMargins property to true. This will make the printer component to ignore the hard margins of the physical printer. The printer component prints as if the hard margins did not exist and the whole page in the physical printer was available for printing. As the physical printer cannot really print on the hard margins, PDF page content over the margins gets clipped or do not get printed.

This is not a problem as PDF pages usually incorporate white space along all four edges. (Users tend to treat the white space as margins but PDF internally does not have any concept of margins.)

When the OffsetHardMargins property is set to true, no viewable content will be lost so long as the:

• PDF page size is less than or equal to the printer page size and
• PDF page does not have any content that fall over the hard margins of the printer
