[FIX] hw_escpos: complying to barcode method A
[FIX] hw_escpos: complying to barcode method A

Have a XMLReceipt with the line:
<barcode encoding="CODE39">123456789</barcode>

Print the receipt.

Before this commit, jibbrish characters were printed and also kinda 'broke'
the spacing between commands
e.g. If you add an EAN13 barcode below the code39 it would have failed to print correctly too

After this commit, everything prints correctly
