Multi-label printing enables the building of templates with a certain layout using different labels from the existing list that can be printed on pre-fabricated special multi-label page.
You can access the setup from the Reports icon at the bottom of the Edit Media window.
In the central top part of the window, under Current, you can Modify the Default or add a New template:
New: Create a new template. Type a name for the template and press OK.
Save: Save changes to a template. As soon as you "Save" the grey label will have the content of the media window.
Modify Setup: To set/modify the Orientation: Landscape or Portrait.
Next you have to define the Page Size In Points. Please see here for an overview on page sizes in points.
The page border will be marked in bright yellow.
Delete: To delete a template.
Sort By Name: To sort template names alphabetically.
Now click on the menu icon at the top left corner and add the labels that you want to print on the multi-label page and arrange on the page:
Add Label: Add a label to be included in the multi-label print template. Once selected it appears as grey box and you can move to the correct position on the page.
Delete Selected Labels: Select on one or more labels by holding the Ctrl key and clicking on them. Then select this option to delete them from the current template.
Select All: To highlight all labels from the current template.
Clear All Sources: This option will clear the Media information on all labels on the current template.
