Barcode 39 ZPL too wide
I don't know if I'm right here, but I should print a barcode 39 and it is too wide for our label...
Here are the ZPL commands I used (printer is a Zebra ZM400):
I tried using the ^BY1 Command but then it is too small - so the scanner isn't able to read it.
The width should have max 8,5cm. Now it has about 11,5 cm.
Could you help me please?
Thanks in advance!

I see you are composing the ZPL commands directly in the SAP form.
From the ZPL2 manual I see that width and height parameters of barcodes can be set via the ^BY command ("Barcode Field Default"):
w = module (narrow bar) width in dots (1 ..10)
r = wide bar to narrow bar width ratio (2.0 ... 3.0)
h = height of bars in dots (1..32000)
Attention: according to the manual, these settings stay in effect for consecutive barcodes as well!
