Printing postage directly on an envelope is possible, but only under specific conditions and through approved USPS or third‑party mailing systems.
While home printers can print addresses and designs, postage itself must be generated using authorized tools to remain valid for mailing in the United States.
What Does “Printing Postage” Actually Mean?
Printing postage does not mean simply typing a stamp value or image on an envelope. USPS requires:
A unique barcode linked to payment
A valid postage amount
A USPS‑approved format
Tracking data (for many services)
Without these elements, the envelope will be rejected.
