The clerk at my post office was able to enter the alphanumeric QR code. At first, she didn't think she could, but she tried again, and whatever she did, it worked. But my post office and clerk must be exceptional, (note not in large city), because the person to whom I sent a gift that was already damaged when shipped, went to two post offices and neither could manage the manual alphnumeric QR code entry.
At one post office she was told that if she could get the QR code image on her phone device, it could be - transferred? - to the post office screen or some such. I am incompetent when it comes to screen shots - or maybe it is this reconfigured, used computer I use - but I did manage to send her the QR code image. Having heard nothing from her, I can figure it did not work.
I had also spent close to an hour on the telephone with a very helpful federal-level USPS technical engineer, and the bottom line seemed to be - and I may have gotten this wrong - that each USPS office is "managed" differently.
My own post office has perhaps 3 people working there, so the telephone is not answered. I will need to go there as soon as I can to ask the excellent clerk how she managed to make the alphanumeric QR code work, and print a label that time.
I read that, a couple years ago, there was a problem with eBay codes, but that seemed to be resolved. Does anyone think it is the eBay QR code problem again. Or ? (I am only a buyer and not a selelr - and Returns is probably the wrong forum).
