When I print actual sticky labels, I use this magic combo:
1) CD Stomper Kit
2) Nero 8 Ultra Edition
Nero allows you to burn your data, then gives you the option of printing a label to go with the data. It imports all the data to its Cover Designer, you filter it's input to your desire, then simply choose which labels you are using (Avery, Folex, etc).
It even gives you a choice of which label to print (if you have multiple labels per page).
And more importantly.. it NEVER misses the alignment.
