Solution for Chromebooks Unable to Print via Flashlabel Plugin

Solution for Chromebooks Unable to Print via Flashlabel Plugin

Your printer must be in ChromeOS mode to work with your Chromebook. Please follow these steps:

Step 1: Check printer mode:

Print the self-test page:

1. Ensure the printer is powered on and label paper is loaded (matching the correct paper type).

2. Press and hold the Feeder button for about 5 seconds until you hear two beeps, then release it immediately.

Locate “U-Disk Mode” on the printed test page:

“OFF” = Correct mode (Enable ChromeOS mode).

“ON” = Error mode → Proceed to step two.

Step 2: Switch to ChromeOS mode

(Required if U-Disk mode is “ON”)

1. Ensure the printer is:

Powered on

Loaded with the correct label paper

Press and hold the function key (top button) for approximately 9 seconds.

Release immediately after hearing three beeps.

Step 3: Configure the Flashlabel plugin

1. Install/reinstall the Flashlabel plugin

2. Key points:

If you previously added a printer in a non-ChromeOS mode, remove it and then add it again after switching modes.

Do not close the interface shown in the screenshot below (the interface after clicking Add) — closing it will cause printing to fail.

Still not working?

1. Restart your Chromebook and printer.

2. Ensure the USB cable is securely connected.

3. Update ChromeOS: Settings → About ChromeOS → Check for updates

Note: Before printing, please make sure “U-Disk Mode: Off” is enabled.
