4. Printing the Document.
Not Allowed. Prevents any printing of the document.
Fully Allowed. Choose this option to allow printing up to the maximum resolution

Low Resolution. Restricts printing to a maximum of 150 dpi. During printing, each
page of the PDF is converted to a bitmap file, essentially freezing the display quality of
the text, graphic, or photo content. Since reproduction quality is largely dependent on
resolution, this eliminates much of the detail required for high quality printing.
