Courier labels and reprints
Courier labels are not designed by you. They come from the carrier, already made, when you buy them for a parcel.
Bought, not rendered
Your own label templates are layouts filled in at print time. A courier label is the opposite: a finished thing the carrier produces, carrying their tracking number and their barcode.
It arrives as either ZPL for a thermal label printer, or a PDF where the site has no thermal printer set up.
Buying is Orders' side of this. Packing a fulfilment group, buying the labels, and voiding one you no longer need are covered in buy and print courier labels.
A reprint never re-buys
The part worth knowing, because the alternative would cost money.
When a label is bought, Yessort keeps the label itself — separately from the print job that put it on paper. Reprinting sends those same stored bytes to the printer again.
So a jammed printer, a torn label, a print that vanished into an office printer somewhere: reprinting costs nothing and does not touch the carrier. The same label comes out, with the same tracking number — which is what you want, because the parcel and the carrier's record already agree on it.
If reprinting bought a new label each time, every jam would cost money and leave an unused label on the carrier's account.
Reprint and void are different
Reprint produces the same label again. Same tracking number, nothing bought, nothing cancelled.
Void cancels the label with the carrier. Use it when the parcel is not going — not when the print failed.
Reaching for void after a jam is the mistake: it cancels a perfectly good label and you buy another.
Labels do not live forever
Stored labels are cleared some time after a shipment is delivered or cancelled — around three months.
Long enough for anything operational, and it means a very old shipment may not offer a reprint. Delivered parcels rarely need one.
Which printer
The same cascade as everything else, with one addition: routing rules can match on carrier and service, so a carrier's labels can go to the printer holding their stock.
