HP Color LaserJet Enterprise CM4540 MFP - Software Technical Reference

Because paper-size settings in most software programs override driver settings, it is generally best to
use the driver to set paper size only when you are printing from software programs that do not include
a paper-size setting, such as NotePad, or when you are producing a book or a booklet that does not
require different paper sizes.
NOTE: Certain software programs can override the size command and specify different paper sizes
within a single document.
When you change the print-driver setting to a paper size that is not currently loaded in the product, a
control-panel message appears that prompts you to load the paper size or select another tray.
For information about paper sizes, see Media attributes and commands on page 174 .
When the Settings under the Special Pages section have been changed, the Paper sizes, Paper
source, and Paper type menus change also, offering a variety of options. For more information, see
Special pages on page 81.
