When I print something (Firefox 5 but also other apps), the option "color" is always set to "Color (CMYK)". How do I make "monochrome" or "black & white" the default?

This is a [Kyocera FS-C5100DN](http://www.kyoceramita.eu/index/products/product/fsc5100dn.html) with CUPS 1.4.6-5ubuntu1.3.

**[EDIT]** Output of `lpstat -d -v`:

```
system default destination: FS-C5100DN
device for FS-C5100DN: socket://192.168.0.24

```

So the question is now: Can I change the default somehow on my own computer without changing settings on the server?
