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

  • Browser print margins shrink the 4x6 area even when the CSS page size is correct.
  • Long product titles wrap into too many lines and push content onto a second label.
  • Printer driver scaling is set to fit-to-page instead of actual size.

Use case

When to use this tool

Best for warehouses and small stores that want a compact packing slip for thermal labels without moving to a full invoice app.

Uses print CSS with a 4in x 6in page size.

Includes a compact pick/pack row layout for SKU, quantity, and item title.

Adds optional order barcode and customer note sections.

Keeps the full template starter in the copy box so merchants can test from a clean Order Printer template.

Calls out long title wrapping, multi-line addresses, and notes as the main causes of second-label overflow.

Calls out browser print margins and printer driver scaling before merchants blame the Liquid code.

Frames Zebra, Rollo, DYMO, and other thermal printers as test targets rather than guaranteed identical output.

Gives a practical overflow checklist for long titles, apartment addresses, gift notes, bundles, and five-plus item orders.

Free tool fit

Use the snippet when the edit is narrow.

Generate a starter 4x6 template with compact layout, print CSS, optional barcode, and order-note handling.

  • You know which Shopify Order Printer template you want to edit.
  • You can test in a duplicate template before touching the live one.
  • The field or layout change maps to the Liquid objects listed on this page.

Manual fix fit

Request help when placement is risky.

Buy a polished 4x6 template or request a custom layout for your printer, browser, and packing workflow.

  • Your current template already has custom loops, tables, CSS, or app-specific fields.
  • The snippet works in isolation but prints blank, repeats, or breaks layout in your real template.
  • The document is customer-facing, B2B, VAT, customs, or warehouse-critical and needs careful test notes.

Install steps

Copy into Shopify Order Printer carefully.

The preview uses sample data. Always test the template with real orders before using it for fulfillment, accounting, customs, or customer-facing documents.

  1. Step Create a new Order Printer template for your 4x6 packing slip.
  2. Step Paste the generated full template starter code.
  3. Step Preview a real order with multiple line items and a shipping address.
  4. Step Check long product names, missing SKUs, apartment addresses, order notes, and orders with 5 or more items.
  5. Step In the browser print dialog, test actual size or 100% scale before fit-to-page.
  6. Step For Zebra, Rollo, DYMO, or similar printers, confirm the label preset is 4 x 6 inches and margins are zero or as low as the driver allows.
  7. Step Print one short order and one overflow-risk order before adding barcodes, gift messages, or metafields.
  8. Step Print one test label on the target thermal printer and adjust margins before using it in production.

Problem diagnosis

Match the symptom before changing Liquid.

Use these checks to decide whether the issue is field data, snippet placement, print settings, or a template merge problem.

The 4x6 slip prints on a second label.

Likely cause
Long product titles, multi-line addresses, gift notes, or too many item rows exceed the fixed 4 x 6 inch print area.
Fix
Test one-item, three-item, and five-item orders; shorten optional fields or request a custom layout for bundle-heavy orders.

The layout is too small on Zebra, Rollo, or DYMO.

Likely cause
The browser or printer driver is using fit-to-page, non-zero margins, or the wrong label preset.
Fix
Choose a 4 x 6 preset, print at actual size or 100% scale, and reduce driver margins before editing the Liquid code.

Barcode or SKU rows are hard to read.

Likely cause
The 4x6 template is trying to fit too many columns or optional fields into a compact item row.
Fix
Keep the first version to title, SKU, quantity, and one optional barcode or note field, then test on the target printer.

The barcode is clipped or too close to the label edge.

Likely cause
The printable area from the browser or thermal printer driver is smaller than the CSS page box.
Fix
Reduce nearby columns, keep the barcode away from the edge, and test actual-size printing before adding more fields.

Print preview looks fine but the physical label cuts off content.

Likely cause
The printer driver, saved preset, browser margins, or label stock has a smaller printable area than the preview suggests.
Fix
Test the real printer with actual size, zero or minimum margins, one short order, and one long address or multi-item order before trusting the template.

Shipping label expectations do not match the output.

Likely cause
A Shopify Order Printer packing slip is being used when the workflow actually needs a carrier postage label.
Fix
Use this page for warehouse packing slips only; carrier labels still come from shipping or fulfillment software.

FAQ

Common Shopify Order Printer issues

Will this fit every thermal printer?

It is a 4x6 starter. Printer drivers and browser print dialogs can add margins, so test and adjust before using it live.

Should I use fit-to-page or actual size?

Start with actual size or 100% scale. Fit-to-page can shrink the design and make barcodes or item rows harder to read.

What should I check for Zebra, Rollo, or DYMO printers?

Use a 4 x 6 label preset, keep margins at zero or the driver minimum, disable unexpected scaling, and run a real test print before editing the template further.

Why does a long product title push the slip onto a second label?

4x6 space is tight. Shorten displayed titles, reduce optional columns, or request a custom layout for bundle-heavy orders.

How many items can fit on one 4x6 packing slip?

It depends on title length, address length, notes, and optional fields. Test 1-item, 3-item, and 5-item orders before using the layout in the warehouse.

What should I test before saving a 4x6 Order Printer template?

Preview a short order, a multi-item order, a long apartment address, a missing SKU, a gift note, and a long product title. Then print at actual size on the target thermal printer.

Can I add barcodes and metafields to this template?

Yes. Use the barcode or metafield generators first, then paste their snippets into the 4x6 template.

Is this a shipping label?

No. It is a packing slip template for Shopify Order Printer, not a carrier label or postage label.

Common errors

Watch these before saving

  • Browser print margins shrink the 4x6 area even when the CSS page size is correct.
  • Long product titles wrap into too many lines and push content onto a second label.
  • Printer driver scaling is set to fit-to-page instead of actual size.
  • The thermal printer uses a saved preset with non-zero margins.
  • Too many optional fields are added before the base 4x6 layout is proven on real orders.
  • Address lines, gift notes, or bundle names are longer than the compact label can safely hold.
  • A packing slip is mistaken for a carrier shipping label or postage label.

Limits

What this does not replace

  • A 4x6 packing slip is not a carrier shipping label or postage label.
  • Thermal printer drivers and browser print dialogs may still need margin tuning.
  • Zebra, Rollo, DYMO, and browser combinations can render margins slightly differently.
  • Large orders may need a multi-page packing slip instead of forcing every item onto one label.
  • Warehouse-specific layouts with bins, bundles, or custom pick paths should be reviewed manually.
