Label Home

I am using a ZD620 with Zebra 10010054 Barcode Labels.

These are 2.25"x1.375"

Using Zebra Designer with this label size, print items do not appear until about Y=0.36

In code, setting the Label header to 0,0 misses the left hand part of the print.

I have to set the LH to ^LH50,0 in order to see the left part of the text.

I am completely mistified. Why is 0,0 NOT the top left of the label?
