    [FIX] hw_escpos: complying to barcode method A
    
    Have a XMLReceipt with the line:
    123456789
    
    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
