Inverse Printing

Possible Artifacts

When printing a solid black background, the print head needs to warm up otherwise it will leave artifacts at the bottom of the first label. This problem is solved by creating a Leader that is printed before the list of tags. This can be thrown away.

On the other end of the spectrum, the print head begins to overheat after about 200cm (20 labels) and text can become unreadable, so when this threshold is reached, a Split function activates that allows splitting up the print job into specifiable smaller chunks.

Editing Templates

To implement printing white text on a black background, we make a copy of the standard template file and invert it, storing the result in tmp/inverses. This means that if you make a change to one of the template files, you must regenerate the inverse files by going to Menu > Control Panel > Regenerate Inverses
