ZPL - how to insert dateTime string in QR code?-CodePudding

I have ZPL like this, it prints a QR code

^XA

^FO50,100
^BQN,2,5,Q
^FD
Hello world!
Some data
Printed on: dateTimeString
^FS

^XZ

What to put in place of dateTimeString so that the following appears when the QR is scanned

Hello world!
Some data
Printed on: 29-Apr-2022 15:35:54

The printer is Zebra ZD421, if that matters. Thanks

Assuming the RTC is correctly set on the printer, have you tried to use the date\time wildcard available in ZPL? Just tested the following code and it did the job

^XA
^FO50,100
^BQN,2,5,Q
^FH\^FC%,{,#
^FDLA,Hello world!\0D\0ASome data %d-%b-%Y %H:%M:%S^FS
^PQ1,0,1,Y
^XZ

The code would have to be in the scanning device/program, not on the printing device.
