today  I almost sent a book to the wrong person

I had 5 requests today and i accidentally printed one label twice (lucky i didn't use the  PBS postage )

and i caught my mistake before i mailed it but i did wonder what would happen had i printed the PBS postage would i be out the

postage money?

In a word yes!!

i don't use printable postage, but i know if you print the same label twice using PBS-DC it knows you already printed it once and doesn't charge you a second time if you need to reprint the label.  (which i've had to do when the printer ran out of ink, or there was a paper jam.)  i imagine it's the same with printable postage.

i did a quick search on printable postage in the help center, and it said:

Can I reprint the wrapper?  Will I be charged again?

• Yes you can reprint the wrapper.  No, you won't be charged again.
• To reprint, just click Print Wrapper (or RePrint Wrapper, if you have marked the book mailed already) on the request, and reprint from the Wrapper Settings page that comes up.
• Of course each wrapper can be used only once, to send one shipment.

Ellen is correct, you would not be out additional money because it would be reprinting the postage you already paid for to send the correct book. The system allows you to reprint it while it is still valid postage (I think up to 24 hours after the date) in case you lose or damage it.
