PowerShell script to set black and white/grayscale on Xerox Phaser printers

[SandraBeier]

We manage a large number of Xerox printers, is there a script to set the printers to black and white printing?

The only alternative way is to manually going to the devices and printers > printing preferences > image options > tick the box "Xerox Black and White conversion"

Any help would be much appreciated.

Even if I get this worked out, something like Adobe will come along which will totally ignore whatever color preferences are in your windows queue and print in colour anyway, madlad of an app it is.
