Force secure print without the option to change it?

Hi all,

Somehow, our Xerox printers (both WorkCentre 5655) have been configured so that the only option under "Job Type" within the printer properties is "Secure Print" - it's grayed out so it can't be selected at all (see attached screenshot). For the life of me I can't figure out how it was forced like this.

I am creating a new print server to replace the one we are currently using and would really like to force the Secure Print option again. Anyone else come across this before and recall how it was done?

Thanks!
