Universal Control Commands

This section describes control commands that are unique to the printer. Universal control commands can be used in any emulation mode.

Before using these commands, read the previous section (Control Commands—An Introduction). It describes the typographic conventions used in this section and contains other information needed to send universal control commands in the correct format.

All universal control commands must begin with the sequence SOH Az or the sequence ESC Az. SOH Az provides maximum compatibility with other printer models and is the sequence documented in this manual.

Note: Control command SOH AzP and control commands that begin with the sequence SOH AzZ are reserved for internal use within the printer. Character sequences that begin with these strings causes unpredictable action.

Universal control commands for formatting and printing bar codes are shown for reference in this section. See Appendix E for complete information.
