Install wizard

Place the snippet before testing output.

1
Template area

New full template

2
Paste target

Replace a duplicate 4x6 test template, not the live invoice first.

3
Test order

One, three, and five item orders on the target printer

Paste location

Use this as a duplicate full template first, then tune margins in the browser and printer driver.

Test checklist

  • Duplicate the Shopify Order Printer template before editing the live one.
  • Preview with the regular order.
  • Test actual size or 100% scale before fit-to-page in the print dialog.
  • Print or save one test preview before using the template in production.

Common failure

  • Replacing a working template without saving a backup first.
  • Adding custom fields before the base invoice or packing slip prints cleanly.
  • Using variables from theme Liquid that are not available in Order Printer templates.

FAQ

Common Shopify Order Printer issues

Is this a Shopify app?

No. It is an independent code tool for Shopify Order Printer templates.

Should I overwrite my current template?

No. Create a duplicate or new template first, then test with real orders before replacing anything.

Can this generate invoice and packing slip templates?

It can create starter code and point you to specific snippets. Polished full templates are better handled as a code fix.
