I'm currently sending my labels to be printed at a shop. It usually takes a week or two and the price is fine for runs over 1000 each.
This is good for our established products, but not too useful for short runs, tests, small modifications, etc.
So I'm thinking a full color label printer would help. It needs to print 4×6 labels, with enough quality to look professional on the shelf on any retail store. And of course, spending as little as possible.
What brands & models people here are happy with?
