Exercise 1: Copy Files to a USB Flash Drive and Perform USB Mirror

On your USB flash drive, create the following:

A folder called

Zebra

In that folder, three subfolders:

appl

commands

files

In the

/appl

folder, place a copy of the latest firmware for your printer.

Avoid underscores in the filenames. Some functions may NOT work properly if there are underscores. Use periods instead.

In the

/files

folder, place the following file:

ZEBRA.BMP

In the

/commands

folder, place the following files:

SAMPLELABEL.TXT

and

LOGO.ZPL

.

Insert the USB flash drive into a USB host port situated on the front of your printer.

Observe the user interface and wait for the following:

If the firmware on the USB flash drive is different than what is on the printer, the firmware downloads to the printer. The printer then restarts and prints a printer configuration label. (If there is no firmware on the USB flash drive or if the firmware version is the same, the printer skips this action.)

The printer downloads the files in the

/files

folder and briefly shows on the display and, in case of printers that have a Color Touch display, the names of the files that are downloading to the printer from the USB drive.

The printer executes any files you added to the

/commands

folder.

The printer restarts, then displays the message

MIRROR PROCESSING FINISHED.

Remove the USB Flash drive from the printer.
