Here is my experience with ZPL commands.
But little customizing of SAP device type is necessary.
1, copy device type LZEBU3 to ZLZEBU3
2, double click on the Z* device type, change driver to Zebra programming language 2, character set for Aisan language need to be maintained as well.
3, Configured the printer as ZLZEBU3/U(access method U can be used directly for Zebra printers).
4, perfrom print test.
Addtional comment, if the test has problem with print control, please define print control as well.
