I have a ZT410 printer and I have an application that requires me to read an EPC Gen2 tag's TID to the host computer and then print the same label. The computer will do some heavy processing (including querying our ERP database) and then print and encode the label with data related to that TID that was read before.
My problem is that I could not find a way to just read the TID without feeding the label that should later be printed.
I'm trying to read the TID using the following ZPL commands:
Is there a way to read the RFID data without feeding a label or to rewind one label before printing?
Unfortunately you are correct that there is no way at this time to read the TID prior to encoding. The ZPL Manual shows how to encode the TID into the tag data and send it back to your host after encoding, but not before. We have been working with the product team to try and find ways around this limitation, but so far have not found any way.
