Printer Driver Help
Each printer driver has help screens that can be activated either from the Help
button, the F1 key, or a question mark symbol in the upper right corner in the
printer driver (depending on the Windows operating system used). These help
screens give detailed information about the specific driver. Printer driver help
is separate from the software application help.
