A shipping label should be reviewed before printing, especially when it comes from a converted file or a batch with many orders.
Check the recipient information
Confirm the recipient name, street, number, postal code, city and state or region. A visually perfect label can still fail operationally if the address content is incomplete or clipped.
Pay special attention to long names and address lines, because they are more likely to wrap or extend outside the intended area.
Check the sender information
Sender data is often printed in a smaller font than the recipient block. Make sure it remains readable at the printer resolution you use.
If the text is visible on screen but weak on paper, the issue may be related to rasterization, print darkness, DPI or the original font dimensions.
Inspect barcodes and QR codes
Barcodes should have clean edges, consistent bars and enough blank space around them. QR codes should remain square and free from overlapping text or graphics.
Do not judge barcode quality only by appearance. When possible, scan a test print using the same workflow used in your operation.
Confirm size, orientation and page count
Make sure the PDF page matches your label stock, usually 4 × 6 inches for common shipping operations. Also confirm portrait or landscape orientation and the number of useful pages.
Blank pages in a batch waste labels and can shift the relationship between order lists and printed labels, so removing genuinely empty pages is valuable.
Print a test before a large batch
After changing any part of the workflow, print one sample first. This is faster than discovering a scaling or readability problem after dozens of labels have been printed.
Keep the test process simple: visual review, barcode scan and comparison with the order information.

What is the most important part of a shipping label to check?
Recipient data and the machine-readable codes are the highest-priority items.
Why is text readable on screen but not on a thermal printer?
Small antialiased text can lose edge pixels when converted to monochrome, and printer darkness or DPI can also affect readability.
Should I scan every barcode?
For large batches that may be impractical, but scanning test labels after workflow changes is a good practice.
