Zebra Australia Post label settings for ZD421, GK420d and ZD220
Get paper size, scale and calibration guidance for Zebra thermal printers printing MyPost Business labels.
Recommended settings
Zebra + Australia Post labels
Paper size
Convert/crop the PDF to 4x6 or 100x150mm first
Scale
Do not shrink A4 onto the label. Crop/convert first, then print at 100%.
Orientation
Portrait unless the preview is sideways
Driver tip
Use Zebra Setup Utilities or the driver preferences to set label width/height before printing.
Calibration
Calibrate media after changing rolls; Zebra drift is often calibration or sensor position.
Your input is A4, so the label will usually print tiny unless it is cropped first.
Use Preview or Acrobat. Open More Settings and confirm paper size before printing.
Zebra settings for MyPost Business labels
Start by making sure your label PDF is not a full A4 page. If it is A4, change MyPost Business to A6 / one-label-per-page or crop the PDF first. Then set the Zebra printer paper size to 100x150mm or 4x6 inches and print at Actual Size / 100%.
FAQ
Can Zebra printers print Australia Post labels?
Yes. Zebra thermal printers can print Australia Post and MyPost Business labels when the PDF is 4x6, A6 or 100x150mm and the driver paper size matches your label stock.
Why are my labels printing too small?
You are probably sending an A4 PDF to a thermal printer. Convert or crop the PDF first, then print at Actual Size / 100%.
What paper size should I choose?
Use 100x150mm or 4x6 inches. If your driver does not show it, create a custom size that matches your label stock.
