Problem

I have tried printing a Deutsche Post shipping label and am seeing an error returned:

The given data contains invalid control characters. Characters with the following ascii decimal codes are not renderable: [1593, 1576, 1583, 1575, 1604, 1585, 1581, 1605, 1606, 1605, 1581, 1605, 1583]

Solution

The error means that the order address details contain non-Latin characters which need to be manually replaced with Latin characters.

To fix this, go to Orders > Open Orders > click on the Order in question > Customer tab > Edit > and adjust the Address information. After that, save the changes and try to print once more.

If the error message will be the same, feel free to contact Linnworks Technical Support for help!
