Sometimes when printing off DPD Labels you will encounter this error:
This is because DPD Labels by default will expire after 24 hours. The solution to this is to rebook the label.
If you are often booking in labels more than 24 hours prior to printing, please contact support at 0117 403 4313 or call us at support@shiptheory.com and we can turn an account specific setting on to help with this.
