Business Cards, Labels and Unix?

Scott Taylor asks: "I've recently started my own company, and after reading The Pragmatic Programmer, and Unix Power Tools I'm interested in removing the need for Microsoft Word to make my business cards and labels. I would like to use a command line solution. One where I can update a configuration file, run make and out comes a label or business card from the printer. Unfortunately I have little experience with text formatting tools other than LaTeX. What would be the best Unix tool to use to create proper templates for Avery labels. Can it support color and graphics? What about printing to color ink jet printers?"
