Usage¶

To use Simple ZPL2 in a project:

from simple_zpl2 import Formatter

# Each label is built with a Formatter object
# The below code would generally be built into a method to create the object or both create and print.
zpl = Formatter()
zpl.add_field_origin(20, 20)
zpl.add_barcode_qr(1, 2, zpl.QR_ERROR_CORRECTION_STANDARD)
zpl.add_field_data('This is data inside a QR code.  This is a barcode often read by cell phones.')

You can view the zpl encoded text:

print(zpl.zpl_text)

Using a web service to render the label as PNG:

from PIL import Image
import io

# Get PNG byte array
png = zpl.render_png(label_width=2, label_height=1)
# render fake file from bytes
fake_file = io.BytesIO(png)
img = Image.open(fake_file)
# Open image with the default image viewer on your system
img.show()

Print label to network based label printer:

from simple_zpl2 import NetworkPrinter

prn = NetworkPrinter('192.168.40.1')
prn.print_zpl(zpl)
