Settings
Packing slip settings control the layout and content of every packing slip generated. All settings can be updated at any time and take effect on the next generated packing slip.
Page size
Controls the physical dimensions of the generated PDF. Choose a page size that matches your printer and workflow.
| Page size↕ | Dimensions↕ | Best for↕ |
|---|---|---|
| 4x6 | 4" x 6" | Thermal label printers. This is the standard label size and enables merging with shipping labels into a single print job. |
| 4x8 | 4" x 8" | Thermal printers that support an extended format, useful when packing slips have more content than a 4x6 can fit. |
| Letter (default) | 8.5" x 11" | Standard desktop printers. Best for packing slips with many items or when a full-page document is preferred. |
Branding
- Logo — Your organization's logo displayed at the top of every packing slip.
- Header text — Custom text displayed below your organization name and logo.
- Footer text — Custom text displayed at the bottom of the page.
- Custom notes — Freeform text displayed between the item list and barcodes. Useful for return instructions, thank-you messages, or promotional content.
Item display
These settings control what product information appears on the packing slip.
| Setting↕ | Default↕ | Description↕ |
|---|---|---|
| Show item images | Off | Display a thumbnail image for each item in the carton. |
| Show item prices | Off | Display the price of each individual item. |
| Show order total | Off | Display the total order amount. |
Barcodes
Up to three barcodes can be included at the bottom of each packing slip for scanning during fulfillment.
| Setting↕ | Default↕ | Description↕ |
|---|---|---|
| Tracking number barcode | On | A barcode encoding the carrier tracking number. |
| Shipment ID barcode | Off | A barcode encoding the Zonos shipment ID. |
| Order ID barcode | Off | A barcode encoding the merchant order ID. |
Merging with shipping labels
When packing slips are generated as part of a batch shipment job, the system can merge them with shipping labels into a single combined PDF. This makes printing more convenient since labels and their corresponding packing slips come out together in one print job.
When merging happens
Packing slips and labels are merged into a single interleaved PDF when all of the following conditions are met:
- Packing slip generation is enabled on the batch job.
- The label format is PDF (not ZPL).
- The packing slip page size is set to 4x6.
When merged, labels and packing slips are interleaved so that each label is immediately followed by its packing slip. The result is a single combined file — no separate packing slip file is produced.
When merging does not happen
If any of the above conditions are not met, labels and packing slips are produced as separate files.
This occurs when:
- The label format is ZPL — ZPL is a printer command language, not a PDF, so it cannot be combined with packing slip PDFs.
- The packing slip page size is 4x8 or Letter — these don't match the 4x6 label dimensions, so interleaving them would produce inconsistent page sizes in a single document.
Generation
Single packing slip
A packing slip can be generated for an individual shipment carton at any time. If a packing slip has already been generated for a carton, it can be regenerated to pick up any changes to settings or shipment data.
Batch shipment jobs
When creating a batch shipment job, packing slip generation can be enabled. Packing slips are then generated automatically for every shipment in the batch, and the merge behavior described above determines how they are combined with labels.
Packing slips
Generate printable packing slips for your shipments.Packing slips are printable documents included with shipments that summarize the contents of each carton. They can be generated individually, in bulk, or automatically as part of a batch shipment job.
Each packing slip is tied to a single package and includes shipment details, addresses, item information, and optional barcodes.
