I found some pre-gummed label-making paper at my LHBS the other day - 1 pack contains eighteen 8 1/2 x 11 sheets for around $6. Just format your design to fit as many labels on one sheet (based on desired label size, of course) and slip these sheets into the printer and let 'er rip. Cut, moisten, and slap onto your bottles. Says they're laser safe and easily removed, and comes in different colors!
