Maxed out the error correction on QR code generation for vastly improved recognition. The trade-off is that the amount of bytes that can be stored are reduced.

f7a2caee72 Actually use the barcode height and width parameters 
(And reverse their order in the method signature so corrections to the

check whether this is the solution for #26

4e1f9db5c7 Make the structure of the ESC/POS commands less opaque 
(The commands are intended to be readable by people who grew up with ANSI
