Yes. There are some basic templates provided for Avery stocks.

Click on the template. It opens in Google. You can save and close and keep it for futher use.
Reopening the template will allow you to change and add your infomation and print the labels.
At the time this was written, I contacted Avery and Google had not determined if more templates would be added to the selection of templates on the Google site.
