Configurations for using ZPL instructions in printer files??

Hi

I need some help in including  the ZPL language in an AS400 printer file.
We are planning to use a Zebra printer for printing bar codes.  However
when i compile my printer file which contains the ZPL language it does not
compile. Do we have any specific properties which need to be changed when
compiling the printer file?

We have already created an outque for the printer with the following
properties.
                 Work with Output Queue Description

Queue:   ZBR1_PRINT     Library:   QUSRSYS
