ZPL Basics

The ZPL Command

P1026208-001 Rev. B Software Integrator Guide 10/29/2010

If the default value for a command parameter suits your application, you need not specify

that parameter. However, parameters are “position-specific.” If you want to change just the

third parameter, for example, you must indicate that it is the third parameter that you want

to change. To do so, use a comma, the ZPL delimiter character, to mark each parameter’s

place (i.e. ^AA,,60). If you enter a parameter and all further parameters to the right are to

be defaulted, then no further commas are required.

Many commands are able to used global default and parameter settings. Common global

parameter settings are field orientation, font selection, font encoding method (^CI), bar

code (height, X-width and narrow to wide ratio), etc. to list some examples.
