How To Clear a Datamax Printer Buffer Before Each Job

Description

This procedure is useful in an automated print and apply scenario where a job for 2000 labels will be sent, but only 1900+ will be printed. When this happens and another job is sent by default, the new job will not start printing until the remaining unprinted labels from the previous job are exhausted. To prevent this, the printer buffer must be cleared so that the new job will begin printing immediately.
