Label stretching inconsistently 追蹤

Virender Atri

We are printing Label through Innovatum Robar which in-turn uses Bartender. We are experiencing issues with a template that prints on 170 XiIII Plus 300 DPi. We are using Seagull scientific Driver for the same. 

The template used to print fine but off late, the bottom part of the label is getting cut off. Seems like the label is being stretched and thus not getting printed on the label stock. Any help to identify the issue will be appreciated.
