Hi timdiam,

Do you mind to tell me please what values are you trying for width and height 
of the barcode you want to print out?

It doesn't matter what values were provided because, aside from some broken 
range checks, your code ignores those parameters.

(You're applying the height range check to the width value and vice-versa)

A bar width of 3 (\x03) and height of 100 (\x64) are hard-coded in constants.py

Since I just fixed it for my own use, here's the patch:

(Sorry about the different format. I fixed it after I rewrote constants.py to 
acknowledge that ESC/POS is intended to take the form of human-readable 
sequences similar to DOS ansi.sys escape codes.)
