How can I permanently force Xerox secure printing?
In Windows there is an opportunity to save individual, but permanent default settings for each application.  I'm sure the same option is there for Mac users as well.

Open the print driver settings.  Do the necessary adjustemnts to black-white vs color, one-sided or two-sided printing eg, and choose secure print.  The before pressing "print" choose the "save print defualts" ....  (I'm nt a Mac user so I cannot say where precisely that option is found.)
