Using USB Host for Firmware Updates
The USB host port allows you to connect an USB Flash drive to the printer to perform firmware updates.
This is an example of using the powerful printer management, Zebra Mirror functions. Refer to the ZPL
Programming Guide — Mirror and Set-Get-Do (SGD) usb.mirror commands operation.
NOTE: Go to About on page 11 for information and support links for your specific printer model.
IMPORTANT: Supports USB Flash drives (or “thumb drive” or “memory stick”) up to 1 Terabyte (TB). The
printer will not recognize drives larger than 1 TB.
Flash Drive Preparation and Firmware Update
1. On your USB Flash Drive, create the following:
a folder called Zebra
in that folder, create three sub-directories:
appl
commands
files
2. In the /appl folder, place a copy of the latest firmware for your printer.
3. Load the printer with media. Go to Loading Roll Media on page 158.
4. Insert the USB Flash drive into the USB host port on your printer.
5. Observe the user interface and wait.
If the firmware version on the USB Flash drive is different than the version installed on the printer, the
firmware will download to the printer. The data indicator will flash green while the firmware is
downloading. The printer will restart with all indicators flashing. When the firmware update has
completed, the
STATUS indicator will display solid Green as the firmware is validated and installed.
The ZD621 printer with a Color Touch Display will display firmware download status messages on the
screen (and the screen shows the firmware version). A printer Configuration Report is automatically
printed and the firmware update has been completed.
6. Remove the USB Flash drive from the printer.
