How to print FNSKU labels on a MUNBYN ITPP941 (2 × 1 in)
Set the paper size to 2 × 1 in (51 × 25 mm) in the MUNBYN ITPP941 driver, print at Scale 100% with margins set to None, and print a page that is exactly one 2 × 1 in label. Stickready turns Amazon’s label PDF into that page in your browser, with the barcode rebuilt for the printer’s dots, opens the print dialog at that size, and remembers your printer’s offset after one test label.
The settings

MUNBYN’s 4-inch printers handle 2 × 1 in rolls fine, but the paper size must be added in the driver, otherwise the default 4 × 6 page is shrunk onto your little label. Run the auto label-learning after every roll change.
Set up the MUNBYN ITPP941 once
- Add the paper size. Printing Preferences (Windows) or the printer’s Options (Mac): add the label size as a custom paper size.
- Teach it the label. Hold the feed button until it beeps to run the auto label-learning.
- Make the labels. Drop Seller Central’s label PDF into Stickready (any layout, including the 30-up sheet), pick MUNBYN ITPP941 and 2 × 1 in, and press Print. The print dialog opens at exactly that page size, at 100%; Download PDF is there too.
- Print one test label and scan it with your phone. If it’s off by a millimeter, measure the two gaps on Stickready’s test label once and it’s fixed for good.
When it goes wrong
The sides are cut off
The page is bigger than the label. Seller Central’s PDF is a Letter page (or a 2.625 in sheet label), and the printer crops whatever doesn’t fit. Use Stickready’s Print button so the page is exactly one 2 × 1 in label, print at Scale 100%, and keep the bars inside a 2 mm margin.
Two labels per sticker, or the label is tiny
The print dialog is shrinking a big page to fit, usually “Fit to page” or “Scale to fit”. Set Scale to 100% (Actual size) and choose 2 × 1 in as the paper size, not Letter.
A blank label between every label
The printer thinks the labels are longer than they are: the scale, the margins or the driver’s paper size don’t match. Hold the feed button until it beeps to run the auto label-learning. Also check that the paper size in the driver is 2 × 1 in (51 × 25 mm), not 4 × 6 in, with Margins None.
Everything is shifted a millimeter or two
Every printer feeds a little differently. Print Stickready’s test label (a frame 2 mm inside each edge), measure the left and top gaps, and Stickready moves all future labels by the difference. Saved for this printer.
The barcode won’t scan
Thin bars smeared by heat, or bars squeezed by scaling. Stickready draws every bar as whole printer dots (203 dpi), so check that Scale is 100%, lower the darkness one step if bars look fat, and scan the test label with a phone before the full run.

Questions
What paper size do I pick for 2 × 1 in labels on a MUNBYN ITPP941?
2 × 1 in (51 × 25 mm). Choose it in the print dialog (or add it in the printer driver first), with Scale 100% and margins None.
Is 2 × 1 in big enough for Amazon FNSKU labels?
Yes. Amazon accepts item labels from 1 × 2 in up to 2 × 3 in, and 2 × 1 in (51 × 25 mm) is inside that range.
Do I need special software for the MUNBYN ITPP941?
Only its normal driver. Stickready runs in the browser: its Print button opens your system print dialog at the right page size, and you can also download the PDF and print it from any PDF viewer.
