Cause:
There could be multiple reason for such errors like:
- Device issue
- Driver issue on printer host
Solution to error LZPL driver does not support SAPscript:
I’ll elaborate step by step procedure we had followed to correct the error in our case:
- Check the printer specification:
For our system, physical printer model was ZEBRA ZDesigner S4M.
and the driver used for it was ZDesigner S4M-300dpi ZPL.

Now if you are using centralized print server, make sure Print server has the exactly same printer drivers for the printer.
- Check the correct device type:
T-code: SPAD

Make sure, you are using correct device type.
You can correct the same in Device attributes via t-code: SPAD

In our case, we used the LB_ZEB2 device type, which worked correctly.
Now test print again:
Spool should be successfully completed.

NOTE: In case the device type does not work, try to change device type related to label printing and test again.
