Once you have edited your labels, they are now ready for printing. Or, if you wish to share the labels with others, you can either invite collaborators or viewers with the Share -> Share with others button. If you are working on a project with others, this could be a good way for them to add people or correct address information. If you wish to send this document as an attachment, go to Share -> Email as attachment.
Most of the Google Docs templates for labels are for around six to eight labels per sheet. If you need a large amount of labels created, you should use the Avery Address Labels with logo, 21 per A4 sheet or for return addresses the Avery Return Address Label, Snowflake, 60 per sheet. Just be sure that you buy the correct size labels for the template that you are using.
