Mac OS X print presets

Let's say you have a color laser printer installed in your system but you usually print in black and white.
It is very likely that the printer presets are in color.
So, every time you need to print a document, and you need it B/W, you have to go through the printer settings and choose the appropriate parameters.
That could eventually become annoying.
Yes, it is possible to create one or more personalized presets to choose from, before hitting the Print button, but that is not always the perfect solution.
