If your Zebra mobile printer is disconnecting or timing out during label printing, adjusting the timeout settings can resolve most connection issues. This guide covers the recommended settings for use with Harvest Point.
Understanding Printer Timeouts
Zebra mobile printers have built-in power-saving features that can cause the Bluetooth connection to drop after periods of inactivity. While this saves battery, it can be problematic during harvest operations where printing may be intermittent.
Recommended Timeout Settings
For optimal performance with Harvest Point, we recommend the following settings:
| Setting | Recommended Value | Description |
|---|---|---|
bluetooth.timeout | 0 (disabled) | Prevents Bluetooth from disconnecting due to inactivity |
power.sleep.timeout | 1800 (30 minutes) | Time in seconds before printer enters sleep mode |
power.off.timeout | 0 (disabled) | Prevents automatic power off |
How to Change Timeout Settings
Method 1: Using Zebra Setup Utilities
- Download Zebra Setup Utilities
Download and install Zebra Setup Utilities from the Zebra support website.
- Connect to the Printer
Connect your printer via USB or Bluetooth to your computer.
- Open Printer Settings
Select your printer and click "Configure Printer Settings".
- Navigate to Power Settings
Find the power management or timeout settings section.
- Apply Recommended Settings
Set the timeout values as shown in the table above.
- Save and Restart
Save settings and restart the printer for changes to take effect.
Method 2: Using ZPL Commands
You can also send ZPL commands directly to the printer to configure timeout settings:
! U1 setvar "bluetooth.timeout" "0"
! U1 setvar "power.sleep.timeout" "1800"
! U1 setvar "power.off.timeout" "0"Send these commands via the Zebra Setup Utilities command window or through a terminal program connected to the printer.
Verifying Your Settings
To verify your current timeout settings, send the following command:
! U1 getvar "bluetooth.timeout"
! U1 getvar "power.sleep.timeout"
! U1 getvar "power.off.timeout"Troubleshooting
Printer still disconnects after changing settings
Ensure you've restarted the printer after making changes. Also check that your mobile device's Bluetooth power saving is disabled.
Settings reset after power cycle
Make sure to save settings permanently. Some printers require a specific save command: ! U1 setvar "device.reset" ""
Battery drains quickly with these settings
These settings prioritize connectivity over battery life. For operations with long idle periods, consider using a power.sleep.timeout of 900 (15 minutes) instead.
