Unfortunately they don’t have that option anymore. I’ve been having the same issue. Now I have to screen shot every shipping labels I have just for them to print perfectly to 4x6 labels.
Topic summary
Difficulty changing Shopify shipping labels to 4×6 thermal size; many only see “Print test label” in Shipping settings with no selectable format.
What works for some:
- Create/fulfill an order, purchase the label, then on the Print shipping label page use Print options > Change format to Thermal 4×6 before printing.
- If the option isn’t shown after purchase, void the label and repurchase; the format chooser may reappear. Also select the label printer (e.g., Rollo/Dymo) and 4×6 in the printer dialog.
Earlier guidance:
- Adjust via printer settings and, in Settings > Shipping > Shipping labels, choose Letter (8.5×11) or Thermal (4×6). Test label printing docs were linked. However, several report this setting isn’t clickable.
Ongoing issues:
- Some can’t find the Change format link, or Save doesn’t persist (reverts to 8.5×11). Being the sole owner doesn’t resolve it. Screenshots were shared to show the missing/disabled controls.
Status and outcomes:
- Staff summarized available workarounds (change format at print step; void and reprint if needed). No confirmed platform fix or global default setting provided. The issue remains unresolved for some, with key questions about why the format option is missing or not saving.
