zplgen is a utility library to aid in generating ZPL2 code.
The core idiom is the Command class, which subclasses bytes. Another helper is the Font class.
f_default = Font('V', height=30)
label = bytes()
label += Command.label_start()
label += Command.label_home(30, 0)
label += Command.graphic_circle(x=550, y=15, diameter=100, border=6)
label += Command.field('?', x=560, y=50, font=f_default(45))
label += Command.field(name, x=0, y=135, font=f_default)
label += Command.label_end()
