How to download the label as ZPL
Printer type is an account preference: pick it once and it applies to every later label until you switch back.
- 1Open Sales → Sales preferences → Label printing settings.
- 2Choose “Thermal printer”. The other option, regular printer, delivers a PDF in A4 or 4x6 — that's the one you go back to for PDFs.
- 3If you print the simplified DANFE together with the label, check that option on the same screen: in thermal mode it arrives as code, in the same file.
- 4Go back to Sales, filter orders ready to ship, select the ones going out together and hit Print labels.
What lands in your Downloads folder
A text file — .txt or .zpl depending on the flow — with one ^XA…^XZ block per order: every selected label in a single file. It isn't a PDF and won't open in an image viewer; drop it onto the converter on this page to see each label.
Printing the file directly
With a Zebra, the classic route is sending the file via Zebra Setup Utilities; multi-language printers that auto-detect ZPL print it without extra setup.
The standard size is 100x150 mm at 203 dpi (8 dpmm). If labels come out shifted or clipped, run the label-sensor calibration in the vendor utility.
No ZPL printer? Convert to PDF
Drop the file onto the converter below and download a PDF at the label's exact size — for PPLA printers, regular printers, or just checking the label on screen first.
Because Mercado Livre's file holds every selected order, the PDF comes out with one page per label, in the original order.
Clipped, blank or blurry labels
Clipped at the top: usually sensor calibration — run it from the printer's utility.
Blurry barcode: almost always a PDF printed with “fit to page”. Print at 100% scale and check the driver is set to 4x6 stock, not A4.
Blank: check the roll is direct thermal (scratch it with a fingernail — it should mark) and loaded the right way up.
For developers: ZPL via the API
Mercado Livre's API returns labels as ZPL with GET /shipment_labels?shipment_ids=…&response_type=zpl2, which returns a ZIP holding the text file; use response_type=pdf for PDF. Up to 50 shipments per call.
Drop the returned ZIP onto the converter here to check layouts without wasting label stock.
