How can I change printer Brother DCP 135 C parameters to print in grey scale or in fast normal mode? Tried everything from changing defaults in CUPS to change it by accessing
defenitions-printers-setings. Nothing works.
It always overrides my commands and prints in normal color mode. CUPS already as the default settings in fast normal and grey scale but the printer seems to ignore it. Thanks in advance for anyone who spends time by helping me.
