Symptom-led fix
Follow the symptom that best matches your bad print. Each step points to the safest next tool before you buy postage again.
A full Letter or A4 page is being fitted onto one 4×6 thermal label.
Inspect the PDF page box. Get the issuer's 4×6 format or extract only a complete label area; do not enlarge the miniature output.
Inspect the PDF pageA true 4×6 source prints proportionally smaller on matching 4×6 media.
Confirm 4×6 in the driver, disable Fit, print one blank template, then calculate a correction only if the media path already matches.
Measure the scale errorThe label boundary is correct, but fine lines are fuzzy, gray or broken.
Treat this as print quality, not page scale. Test density, speed, media and printhead condition before another live label.
Run a print-quality testShopify documents Thermal 4 × 6/A6 for label printers and Letter or A4 for desktop printers. Its troubleshooting flow lets you close the print popup, select the correct label size and reprint the original document.
Confirm that the full USPS barcode, tracking number, recipient and return addresses, service text and routing marks are present. A crop caused by the wrong media or orientation should disappear after a correctly formatted reprint.
Do not trim into the barcode or its surrounding white space. USPS Click-N-Ship guidance also says not to tape over barcodes, so attach the corrected label without glossy tape across scan-critical content.
This page cannot promise USPS acceptance. If the Shopify source file itself is incomplete, the package shape prevents flat placement, or any active content remains damaged, use Shopify or USPS support before drop-off.
This page is a practical print-setting checklist, not official carrier policy or a promise that a label will be accepted.
Confirm the current format in your platform or carrier account, keep the original PDF, and stop if a test print is cropped, blurred or incorrectly scaled.
Troubleshooting advice is general. Record the printer model, paper size, PDF viewer and scale setting so you can verify each change.
Only remove unused outer paper. Do not cut barcode whitespace, tracking, address, service or routing content.
Close the print popup, choose the paper format that matches the printer, and click Print shipping labels again.
