I've tried lots of different ways of printing labels.
I've found by far the best method is to use labels made by Avery.
Larger branches of Staples stock them, as do Rymans.
You can then download the 'Avery Wizard' for MS Office from the Avery website and print sheets all the same or with different entries for each label. The Avery software opens within MS Word.
It really is very easy to use and gives good results.
