Don't Work with Metapace T-40 #65

Metapace can understand ESC/POS but I cloud not change barcode width. Barcode is very small. Also QR code is not printed, only the value as text. Are there any tricks to correct this?

Thanks for hints.

I had the same issue with the small barcode. It looks like that the printer uses a different scale for the width. For me only the width 1 (small), 2 (medium), 3 (large) worked.

Here is my example:

.barcode(112233445566, "EAN13", { width: 2, height: 100 })
