^HR - Calibrate RFID Transponder Position
This command initiates an RFID transponder calibration for a specific RFID
label and returns the results to the host computer.
~HS - Host Status Return
The ~HS command returns various printer status information to the host. The
status information is returned in three separate strings, each of which
contains several sub-fields. Currently, three sub-fields contain status
information: the Partial Format flag, the Label Remaining in Batch value,
Communication Setting, Paper Out flag, Pause flag, Label Length, Head Up
flag, Ribbon Out flag, and Label Waiting flag. The remaining sub-fields are
returned with dummy values for the purpose of allowing host applications to
run correctly.
~HS is a preparser command, which is processed immediately when the
command is sent. Before sending the command, set the menu options
“Preparser Command and “Preparser Port” accordingly.
^HW - Host Directory List
This command returns a directory list of objects in a specific memory area
(storage device) back to the host with object names and object size.
Currently, the command only lists the objects stored in DRAM.
^ID - Item Delete
The device naming convention differs as follows:
ZPL device specifiers:
R: DRAM
B: Optional Memory
E: Extra EPROM
Z: Standard EPROM
PPI device specifiers:
R: DRAM
B: FLASH
Z: Standard Fonts
NOTE: The ZGL ^ID command only deletes font (*.FNT and *.ttf) and
graphics logos (*.GRF) from both DRAM and Flash. It does not delete
the stored format (*.ZPL).
^J$E - Switch Emulation
This command is used to switch emulations from ZGL to PGL or VGL:
^J$E PGL
→ Switch to PGL
^J$E VGL
→ Switch to VGL
~JD / JE - Disable/Enable Diagnostics
The hex dump format is different from the ZPL format. In addition,
communication errors may not be displayed. This command also changes the
value of the related front panel option.
