Product Name: Xerox C235 Color Multifunction Printer
Operating System: Linux
I've setup my printer with disabled banner page. But it print always a banner page, doesn't matter from which device. We are using this printer in our house. All members of the family use it from different OS.
The reason must be in the printer itself. If I change the language (English/German) I get a banner page in the selected language.
It says Banner page none (in German)
The firmware is the most current one: CXLBL.076.054
