On a few of our printers, the color tab has disappeared from the Printer Preferences dialog of the print driver (and the printer won't print color from that workstation).
That is, when one issues the print command (Ctrl P -- the print dialog is displayed), then clicks Preferences to view the printer's own preferences dialog... the Color tab has disappeared on three user workstations.
This is a color printer and the printer has tons of toner. The tabs were there just a few days ago. This is not happening on all stations, but the same thing is happening on more than one.
I've already tried removing/reinstalling the driver and telling the new driver to replace / overwrite the current one.
