Recommended MUNBYN settings
MUNBYN ITPP941 or 941B for 4x6 shipping labels
Paper size
Use a 4 in x 6 in paper size and check that the preview fills one label without trimming the barcode quiet zone.
Scale
Actual Size / 100%
Source file
The source page is close to ready. Most remaining risk is paper size, scale, calibration or orientation.
First fix
Print one unpaid test label, scan the barcode with a phone app, then print live postage only after the preview fills the stock cleanly.
Open printer preferences, choose a 4x6 inch or 100x150mm paper size, then keep scale at 100% after the PDF is already label-sized.
Nothing is uploaded or stored. Use this as a pre-print checklist, then print one unpaid test label before a batch.
MUNBYN 4x6 shipping label paper size and scale
MUNBYN shipping-label prints usually go wrong when the PDF page, printer paper preset and physical label stock disagree. For a true 4x6 or 100x150mm shipping label PDF, choose a matching MUNBYN paper preset and print at Actual Size or 100%.
If the print dialog still says Letter, A4 or a custom size you do not recognise, fix the MUNBYN paper preset before changing the artwork. If you need to compare page sizes, use the shipping label print scale calculator first.
If you also print with Rollo, Zebra, Dymo or Brother hardware, use the related printer checkers below. The same carrier PDF can fail differently on each printer because driver presets and calibration rules are not identical.
- Paper size: 4x6 inches, 6x4 inches or 100x150mm.
- Scale: Actual Size or 100% for a label-sized PDF.
- Orientation: portrait unless the preview shows sideways output.
- Calibration: run a MUNBYN calibration after changing stock.
Letter, A4 and multi-label PDFs need a crop first
USPS, Royal Mail, eBay, Etsy, Shopify, AusPost and other shipping workflows can give sellers different PDF layouts. Some files are already one 4x6 label per page. Others put the label on a Letter, A4 or multi-label sheet meant for an office printer.
Do not send the whole office-printer page straight to the MUNBYN queue and hope Fit to page fixes it. Convert the label area into a real 4x6 page with the A4 to 4x6 shipping label converter or check the source file with the shipping label size checker before printing.
MUNBYN calibration checks before changing the PDF
If the label starts too high, too low, feeds extra blank stock or cuts off one edge, calibrate the printer before editing the carrier PDF. Calibration teaches the printer where one label ends and the next begins.
Use the thermal printer test label PDF after calibration. It gives you borders, scale marks and barcode checks without risking paid postage.
Blank MUNBYN labels usually start with stock or heat
A blank MUNBYN label is not always a PDF problem. Check that the label stock is direct thermal, loaded print-side up and seated correctly. Then run a printer self-test before you change carrier settings.
If the self-test prints but the carrier label stays blank, check the PDF preview and print destination. If both fail, use the blank thermal label checker for a fuller stock, queue and print-head checklist.
When LabelChop helps with MUNBYN shipping labels
This checker is best for one MUNBYN setup or one confusing PDF. LabelChop is for sellers who keep getting awkward shipping-label PDFs and want the crop, resize and print step handled automatically.
LabelChop watches your Downloads folder, detects supported shipping-label PDFs, crops them to 4x6 / 100x150mm and prints or saves them for your thermal printer. It helps with PDFs from carrier and marketplace workflows after you already have the file.
FAQ
What MUNBYN settings should I use for 4x6 shipping labels?
Choose a 4x6 inch, 6x4 inch or 100x150mm paper size, print at Actual Size or 100%, and calibrate after changing label stock.
Why are my MUNBYN shipping labels printing too small?
The usual cause is Fit to page, a Letter or A4 paper preset, or sending a full-page carrier PDF directly to the 4x6 thermal printer.
Why does my MUNBYN print blank labels?
Check that the stock is direct thermal, loaded print-side up and calibrated. Run a printer self-test before changing the PDF.
Can MUNBYN print USPS, Royal Mail and marketplace labels?
Yes, when the PDF page and driver paper size match the loaded 4x6 or 100x150mm stock. Awkward A4 or Letter PDFs may need cropping first.
Is LabelChop an official MUNBYN or carrier integration?
No. LabelChop helps with shipping-label PDFs after you have the file. It is not an official MUNBYN, USPS, Royal Mail or carrier integration.
Printing MUNBYN labels every week?
LabelChop automates the crop-and-print step for recurring shipping-label PDFs, so MUNBYN users do not have to fight the same scale settings every day.
