ZD220: Can't get rid of borders

Hello,

Since I changed the media, I have had issues with the printer's alignment. Feeding a new label using the button on the printer is fine; however, even printing a test page led to an offset. I was able to solve this by setting the label size "to set in the printer", not the driver.

However, I still can't print without borders. I have no idea where those come from. In the driver, they're set to 0. The size of the document is only 100mm x 150mm.
