Can you print a shipping label on plain printer paper?
Yes. USPS puts it plainly on its own packing page: you do not need special label sticker paper, you can use regular printer paper, and you tape the printed label to your package with clear packing tape, per usps.com checked 2026-07-28. Carriers scan paper labels every day.
What print quality does the barcode have to meet?
The USPS Parcel Labeling Guide recommends a printer with a minimum resolution of 203 dots per inch, requires the barcode to be printed on a substrate which is uniform in color, sets symbol contrast at 40 percent or better, and expects at least 70 percent of barcodes in a mailing to grade B or above. That is version 3 release 5, read on postalpro.usps.com on 2026-07-28.
What ruins a plain-paper label?
Four things, in rough order of frequency: printing at fit-to-page instead of actual size, a cartridge low enough that the bars go grey, coloured or patterned paper that breaks the uniform-colour rule, and glossy stock that throws the scanner light straight back. None of them are about the paper being cheap.
Does printing on paper cost more to ship?
No. Postage is priced on the package, not on the stationery. The same box quoted on 2026-07-28 from Newark to Atlanta came back at the same numbers regardless of what the label was eventually printed on.
