Formatted printing output

Hi,

I,ve made a functional database table with names, addresses etc of some 
50 members of a group which I serve as secretary.
I've bought Bruce Momjian's book which has been very helpful as far as 
I've gone up to date but...
Now I want to produce formatted print output - mailing labels or print 
envelopes, produce reports etc.
How do I do that?
I'm running Mandrake Linux 8.1

regards
Dave Dartnall.
