I have 21 labels on a page and want to print on them. How do I proceed?
First you will need to scan those labels to make them editable in any image editor then you'll need to edit them. I recommend to use Gimp or Paint.net. Import the files into one of these applications then edit the file to your pleasure and then you can print them back. Make sure the scanning settings are 300 dpi or higher so you'll obtain good quality samples.
